How can data science and statistical analysis be used to improve the shipping and logistics industry?

Is it possible to build a highly effective, multi-faceted, intelligent forecasting system for future financial and economic crises based on artificial intelligence technology in combination with Data Science analytics, Big Data Analytics, Business Intelligence and/or other Industry 4.0 technologies as part of a forecasting system for complex, multi-faceted economic processes in such a way as to reduce the scale of the impact of the paradox of a self-fulfilling prediction and to increase the scale of the paradox of not allowing a predicted crisis to occur due to pre-emptive anti-crisis measures applied?

What do you think about the involvement of artificial intelligence in combination with Data Science, Big Data Analytics, Business Intelligence and/or other Industry 4.0 technologies for the development of sophisticated, complex predictive models for estimating current and forward-looking levels of systemic financial, economic risks, debt of the state's public finance system, systemic credit risks of commercially operating financial institutions and economic entities, forecasting trends in economic developments and predicting future financial and economic crises?

Research and development work is already underway to teach artificial intelligence to 'think', i.e. the conscious thought process realised in the human brain. The aforementioned thinking process, awareness of one's own existence, the ability to think abstractly and critically, and to separate knowledge acquired in the learning process from its processing in the abstract thinking process in the conscious thinking process are just some of the abilities attributed exclusively to humans. However, as part of technological progress and improvements in artificial intelligence technology, attempts are being made to create "thinking" computers or androids, and in the future there may be attempts to create an artificial consciousness that is a digital creation, but which functions in a similar way to human consciousness. At the same time, as part of improving artificial intelligence technology, creating its next generation, teaching artificial intelligence to perform work requiring creativity, systems are being developed to process the ever-increasing amount of data and information stored on Big Data Analytics platform servers and taken, for example, from selected websites. In this way, it may be possible in the future to create "thinking" computers, which, based on online access to the Internet and data downloaded according to the needs of the tasks performed and processing downloaded data and information in real time, will be able to develop predictive models and specific forecasts of future processes and phenomena based on developed models composed of algorithms resulting from previously applied machine learning processes. When such technological solutions become possible, the following question arises, i.e. the question of taking into account in the built intelligent, multifaceted forecasting models known for years paradoxes concerning forecasted phenomena, which are to appear only in the future and there is no 100% certainty that they will appear. Well, among the various paradoxes of this kind, two particular ones can be pointed out. One is the paradox of a self-fulfilling prophecy and the other is the paradox of not allowing a predicted crisis to occur due to pre-emptive anti-crisis measures applied. If these two paradoxes were taken into account within the framework of the intelligent, multi-faceted forecasting models being built, their effect could be correlated asymmetrically and inversely proportional. In view of the above, in the future, once artificial intelligence has been appropriately improved by teaching it to "think" and to process huge amounts of data and information in real time in a multi-criteria, creative manner, it may be possible to build a highly effective, multi-faceted, intelligent forecasting system for future financial and economic crises based on artificial intelligence technology, a system for forecasting complex, multi-faceted economic processes in such a way as to reduce the scale of the impact of the paradox of a self-fulfilling prophecy and increase the scale of the paradox of not allowing a predicted crisis to occur due to pre-emptive anti-crisis measures applied. In terms of multi-criteria processing of large data sets conducted with the involvement of artificial intelligence, Data Science, Big Data Analytics, Business Intelligence and/or other Industry 4. 0 technologies, which make it possible to effectively and increasingly automatically operate on large sets of data and information, thus increasing the possibility of developing advanced, complex forecasting models for estimating current and future levels of systemic financial and economic risks, indebtedness of the state's public finance system, systemic credit risks of commercially operating financial institutions and economic entities, forecasting economic trends and predicting future financial and economic crises.

In view of the above, I address the following questions to the esteemed community of scientists and researchers:

What do you think about this topic?

What is your opinion on this subject?

Please respond,

I invite you all to discuss,

Thank you very much,

I want to learn data science using R, Python, machine learning etc. Anyone who can send me the links for these training courses (up to 6 months) that are legitimate and can be accepted in USA?

I have no specific research topics for a PhD in Data Science.

Which laptop is recommended for data science and managing large datasets among the following options?

Hi there! I'm a Python expert with strong skills in Machine Learning, Data Science, and Data Analysis. I'm eager to join a research team to collaborate on exciting projects. My experience includes supervised/unsupervised learning, and data manipulation using NumPy/Pandas. I'm proficient in statistical analysis. I'm committed to open communication and teamwork for successful outcomes. Let's explore how I can contribute to your research team's endeavors. If you need any person to be in your team to conduct a research and publish it, I will be happy to be in your team.

Fractal analysis and data science are both interdisciplinary fields that complement each other in various ways.

1. Understanding Complex Data: Fractal analysis provides a framework for understanding complex data structures and patterns. Data science deals with large and complex datasets, and fractal analysis techniques help in identifying self-similarity, scaling properties, and patterns within the data. By applying fractal analysis methods, data scientists can gain insights into the underlying structure of the data.

2. Feature Extraction: Fractal analysis enables data scientists to extract meaningful features from datasets. Fractal dimensions, for example, can quantify the complexity or irregularity of patterns in data, which can then be used as features for further analysis. These features can enhance the predictive capabilities of machine learning models and help uncover hidden relationships or anomalies in the data.

3. Data Visualization: Fractal analysis can be used to visualize and represent complex datasets in more intuitive and informative ways. Data visualization is a crucial aspect of data science, as it helps in understanding the data and communicating insights effectively. Fractals, with their visually appealing and self-replicating patterns, can provide a unique and visually rich representation of data.

4. Time Series Analysis: Fractal analysis techniques, such as fractal dimensions and Hurst exponent, can be particularly useful in analyzing time series data. Data scientists often work with time-dependent data, like stock prices, weather data, or sensor measurements. Fractal analysis helps in uncovering long-term dependencies, trends, or self-similar patterns in such data, contributing to forecasting, anomaly detection, and modeling of time series.

5. Dimensionality Reduction: In data science, one often encounters datasets with high dimensions, making it challenging to analyze and extract meaningful insights. Fractal analysis techniques can assist in reducing the dimensionality of the data by identifying the most relevant features and reducing noise or redundancy. This can lead to more efficient and accurate data analysis and modeling

If I want to extend my discussion with an example,

let's say we have a time series dataset of stock market prices over several years. By applying fractal analysis techniques such as the Hurst exponent or box counting, we can identify any underlying fractal patterns in the data. This can help us understand the long-term stability or volatility of the stock market, and potentially predict future trends.

In data science, we can further enhance our understanding of the stock market data by applying various statistical and machine learning techniques. We can build predictive models based on historical price trends, external market factors, and other relevant data. These models can then be used to forecast future stock market behavior and guide investment strategies.

Is there a book or an article to express the relation between fractals and data science with more details and examples?

Hi all - I am looking for an opportunity to review and Data Science and Cyber security paper. Any recommendation will help me.

I need viable project for my masters program in data science

I have looked at data base management and applications, data-sets and their use in different contexts. I have looked at digital in general, and I have noticed that there seems to be a single split:

-binary computers, performing number crunching (basically), and behind this you find the Machine Learning, ML, DL, RL, etc at the root fo the current AI

-quantum computing, still with numbers as key objects, with added probability distributions, randomisation, etc. This deviates from deterministic binary computing but only to a certain extent.

Then, WHAT ABOUT computing "DIRECTLY ON SETS", instead of "speaking of sets" and actually only "extracting vectors of numbers from them"? We can program and operate with non-numerical objects, old languages like LISP and LELISP, where the basic objects are lists of characters of any length and shape have done just that decades ago.

So, to every desktop user of spreadsheets (the degree-zero of data-set analytics) I am saying: you work with matrices, the mathematical name of tables of numbers, you know about data-sets, and about analytics. Why would not YOU put the two together: sets are flexible. Sets are sometimes are incorrectly named "bags" because it sounds fashionable (but bags have holes, they may be of plastic, not reusable, sets are more sustainable, math is clean -joking). It's cool to speak of "bags of words", I don't do that. Sets, why? Sets handle heterogeineity, and they can be formed with anything you need them to contain, in the same way a vehicle can carry people, dogs, potatoes, water, diamonds, paper, sand, computers. Matrices? Matrices nicely "vector-multiply", and are efficient in any area of work, from engineering to accounting to any science or humanities domain. They can be simplified in many cases (eigenvector, eigenvalue, along some geometric directions operations get simple, sometimes the change of reference vectors gives a diagonal matrix with zeros everywhere except on the diagonal, by a simple change of coordinates (geometric transformation).

HOW DO WE DO THAT IN PRACTICE? Compute on SETS NOT ON NUMBERS? One can imagine the huge efficiencies gained in some domains, potentially (new: yet to be explored, maybe BY YOU? IN YOUR AREA). Here is the math, simple, it combines knowledge of 11 years old (basic set theory) and knowledge of 15 years old (basic matrix theory). SEE FOR YOURSELF ,and please POST YOUR VIEW on where and how to apply...

How shipping and logistics industry can be improved using Data science and Statistical analysis methods?

Hi,

I want to predict the traffic vehicle count of different junctions in a city. Right now, I am modelling this problem as a regression problem. So, I am scaling the traffic volume (i.e count of vehicles) between 0 to 1 and using this scaled down attributes for Regression Analysis.

As a part of Regression Analysis, I am using LSTM, where I am using Mean Squared Error (MSE) as the loss function. I am converting the predicted and the actual output to original scale (by using `inverse_transform`) and then calculating the RMSE value.

But, as a result of regression, I am getting output variable in decimal (for example 520.4789), whereas the actual count is an integer ( for example 510 ).

Is there any way, where I will be predicting the output in an integer?

(i.e my model should predict 520 and I do not want to round off to the nearest integer )

If so, what loss function should I use?

As a newcomer to the research field, I am seeking your valuable input and innovative ideas to initiate my research in data science. I am particularly interested in exploring fresh avenues within machine learning, data mining, predictive analytics, and artificial intelligence. Your guidance in formulating a concise yet comprehensive research question would be highly appreciated.

I would be grateful if you could provide me with information (e.g. papers, URLs) on exemplary data science education projects in Asian countries of which you are aware.

I'm a student of DIU and majoring in Data Science ....I would love some idea and options about doing a thesis paper as I've never done it before and am completely new in this sector.

Long since we have come across AI and ML where ML is a subset of AI. Data science has been framed recently. My query is where does data Science fit into this realm of AI and ML?

Is it under AI and above ML or is it a subset of ML or does it include AI or is it an entity having partial overlapping with AI or ML?

How could I find a hybrid conference (in-present + online) to submit a demo paper in data science/data management? I tried searching using WikiCFP, Google search, and the IEEE conference search engine with no luck. These search engines will help find one aspect of the conference (hybrid or accept demo papers), but I cannot match both requirements.

Note: I need to present my demo paper online without traveling.

Any help is appreciated.

I am planning on implementing a time series model, but i already implemented an ARIMA model and it doesn't seem to be robust. For argument sake, I was thinking of implementing (RNN)LSTM Model. How their metrics differ when applied to datasets In general.

The development of innovation and entrepreneurship, including the effective development of innovative startups using new technologies in business, is among the key determinants of a country's economic development. Among the important factors supporting the development of innovativeness and entrepreneurship, apart from system facilitations, a favourable tax system, low interest rates on investment loans, available non-refundable financial subsidies, there is also the issue of the possibility of implementing new technologies, including Industry 4. 0, including, but not limited to, technologies such as artificial intelligence, machine learning, deep learning and Big Data Analytics, Internet of Things, digital twins, multi-criteria simulation models, cloud computing, robots, horizontal and vertical data system integration, additive manufacturing, Blockchain, smart technologies, etc., can be helpful in the process of improving the management of economic entities, including service companies, manufacturing enterprises and innovative start-ups. These information technologies and Industry 4.0 can also help to improve Business Intelligence used in business management. The key issue is the proper combination of applied Industry 4.0 technologies to create computerised platforms supporting the processes of managing both the current, operational functioning of economic entities and in the processes of forecasting the determinants of the development of companies and enterprises, in the creation of forecasting models of simulation of development for a specific economic entity, which may also be an innovative start-up. In recent years, attempts have been made in larger business entities, corporations, financial institutions, including commercial banks, to create computerised Business Intelligence analytical platforms improved through a combination of applied technologies such as machine learning, deep learning and a specific generation of artificial intelligence applied to Big Data Analytics platforms. Such processes for improving Business Intelligence analytical platforms are carried out in order to support the management of the effective operation and development of a commercially operating specific business entity. Therefore, in a situation where specific financial resources are available to create analogous Business Intelligence analytical platforms, it is possible to apply an analogous solution to support the management of the effective operation and development of a commercially functioning specific innovative start-up.

In view of the above, I address the following question to the esteemed community of scientists and researchers:

And what is your opinion on this topic?

Dear ResearchGate Community,

I am reaching out to seek your help in obtaining access to an ecommerce website database to help me predict customer behavior online. The ecommerce business in question must be operating and dealing with Moroccan consumers.

As a researcher in the field of data science, I am interested in exploring the patterns and behaviors of consumers in the Moroccan ecommerce market. However, to do so, I need access to a relevant and up-to-date database.

My research aims to develop predictive models that can help ecommerce businesses in Morocco understand and anticipate customer behavior. By analyzing large sets of data, I hope to uncover trends, preferences, and insights that can improve the customer experience and ultimately increase revenue for these businesses.

Therefore, I am looking for a data set that contains information such as user profiles, product preferences, purchasing histories, and other relevant data points that can help me better understand the behavior of Moroccan ecommerce customers. Ideally, the data set would cover a substantial period of time, and be anonymized to ensure user privacy.

my area of interest are Data Science, Ecommerce, AL, ML Sensor technology.

In recent years, the application of new Industry 4.0 technologies in the process of generating marketing innovations applied to online social media portals has been on the rise. For the purpose of improving marketing communication processes, including advertising campaigns conducted on social media portals and promoting specific individuals, brands of companies, institutions, their product offers, services, etc., sentiment analysis of Internet users' activity in social media is conducted, including analysis of changes in social opinion trends, general social awareness of citizens by verifying the content of banners, posts, entries, comments, etc. entered by Internet users in social media using computerised, analytical Big Data Analytics platforms. I have described this issue in my articles following their publication on my profile of this Research Gate portal. I invite you to collaborate with me on team research projects conducted in this area. Currently, an important developmental issue is also the application of Big Data Analytics platforms used to analyse the sentiment of Internet user activity in social media, which uses new technologies of Industry 4.0, including, among others, artificial intelligence, deep learning, machine learning, etc. Besides, the implementation of artificial intelligence, Big Data Analytics and other Industry 4.0 technologies can help in the process of automated generation of marketing innovations applied on online social media portals. An important issue in this topic is the proper construction of a computerised platform for the automated generation of marketing innovations applied on online social media portals, in which the new generations of Artificial Intelligence, Big Data Analytics and other Industry 4.0 technologies are used.

In view of the above, I address the following question to the esteemed community of scientists and researchers:

What do you think about this topic?

What is your opinion on this subject?

I am developing a Data Science project applied to petrogenetic modeling using whole rock lithogeochemistry to understand the evolution of two different trends of magmatic rocks that would be associated with each other according to the proposed theory. This work will be my Master's Thesis.

However, I am having difficulties in petrogenesis when trying to understand which parameters or elements or elemental ratios could best be used to evaluate the hypothesis if these segments were part of the same source or not. The most accepted geological model for the region is through the passage of a hotspot below the South American Plate during the Meso-Cenozoic.

Although there are controversies with this model, how would it be possible to identify chemical parameters that would affirm or deny the connection between the magmatic assemblages?

Which parameters should I consider in my model or which ones would be better not considered due to complexity or difficulty in understanding the evolution of a given parameter?

The spread of disinformation on social media used by setting up fake profiles and spreading fakenews on these media is becoming increasingly dangerous in terms of the security of not only specific companies and institutions but also the state. The various social media, including those dominating this segment of new online media, however, differ considerably in this respect. The problem is more acute in the case of those social media which are among the most popular and on which mainly young people function, whose world view can be more easily influenced by factual information and other disinformation techniques used on the Internet. Currently, among children and young people, the most popular social media include Tik Tok, Instagram and YouTube. Consequently, in recent months, the development of some social media sites such as Tik Tok is already being restricted by the governments of some countries by banning the use, installation of this application of this portal on smartphones, laptops and other devices used for official purposes by employees of public institutions. These actions are argued by the governments of these countries in order to maintain a certain level of cyber security and reduce the risk of surveillance, theft of data and sensitive, strategic and particularly security-sensitive information of individual institutions, companies and the state. In addition, there have already been more than a few cases of data leaks on other social media portals, telecoms, public institutions, local authorities and others based on hacking into the databases of specific institutions and companies. In Poland, however, the opposite is true. Not only does the organised political group PIS not restrict the use of Tik Tok by employees of public institutions, but it also motivates the use of this portal by politicians of the ruling PIS option to publish videos as part of the ongoing electoral campaign, which would increase the chances of winning parliamentary elections for the third time in autumn this year 2023. According to analysts researching the problem of growing disinformation on the Internet, in highly developed countries it is enough to create 100 000 avatars, i.e. non-existent fictitious persons, created as it were and seemingly functioning thanks to the Internet by creating profiles of these fictitious persons on social media portals referred to as fake profiles created and functioning on these portals, to seriously influence the world view, the general social awareness of Internet users, i.e. usually the majority of citizens in the country. On the other hand, in third world countries, in countries with undemocratic systems of power, all that is needed for this purpose is about 1,000 avatars of these fictitious people with stories modelled, for example, on famous people such as, in Poland, a well-known singer claiming that there is no pandemic and that vaccines are an instrument for increasing control of citizens by the state. The analysis of changes in the world view of Internet users, changes in trends concerning social opinion on specific issues, evaluations of specific product and service offers, brand recognition of companies and institutions can be conducted on the basis of sentiment analysis of changes in the opinion of Internet users using Big Data Analytics. Consequently, this type of analytics can be applied and of great help in detecting factual news disseminated as part of the deliberate spread of disinformation on social media.

In view of the above, I address the following question to the esteemed community of scientists and researchers:

What is your opinion on this topic?

Hi! Germination percentage use to have no normal distribution, and in many cases low replicates limit the sense of its scale transformation. If you have experiencie you can share it with me, I will appreciate it!

I am undergoing my MSc in Data Science. I am looking forward to starting a career in Cancer Data Science. Although my background is Chemical Engineering. I would like useful tips on how to go about it.

Thank you.

How do you think artificial intelligence can affect medicine in real world. There are many science-fiction dreams in this regard!

but how about real-life in the next 2-3 decades!?

please can you pin point the major key aspects of data science and product development in this regards?

Hi

I am teaching a Course in Data Science, and I am looking for a reference on general research design / design of study which can be used is this context.

I am looking for something which is not a full book, but rather of article length that potentially covers a classical approach to research design (i.e. what do you need to consider when doing research) and a view on the same in a data science perspective.

It can of course be a number of articles covering different aspects.

I hope someone has a good idea :-)

please i need suggestions on project topics in data science and recommendation

During my Master's in Archaeology program, I explored network analysis at a beginner level. I am eager to delve deeper into this field for testing innovative methods and theories. I am looking forward to a PhD.

My focus is not solely on social network analysis, but rather the innovative applications of the broad concept of network in archaeological reasoning. My background is in prehistoric archaeology in Northeastern America, but I am open to different cultural areas and historical periods. I have specific ideas/questions suitable for methodological research.

Can you recommend professors, universities, and research groups?

i have been in this DS for over decade and did some work on NN's and come along with Deep Leaning and people started ask this how easy and difficult is this after all you just train a nets with some data, (dont get into that linear or non) all we do is to put that one algo and train and wait , so what is so difficult of it, dont tell me it complex, before use this word , tell me what is complex of have you invented anything or framework no, 99.9 we are just using these technologies that some brought our plate , given this how difficult or easy this deep learning and data science on whole

In recent years, data science has emerged as a promising interdisciplinary subject, and helped understand and analyze actual phenomena with data in multiple areas. The availability and interpretation of large size data that is a vital tool for many businesses and companies has changed business models, and led to creation of new data-driven businesses.

In agriculture including crop improvement programs, both short and long term experiments are conducted, and big size data is generated. However, deep data mining, meaningful interpretation, deeper extraction of knowledge and learning from data sets are more often missing. Whether application of data science is also vital in agriculture including crop improvement for understanding and analyzing the actual phenomena and extracting deeper knowledge??

Many businesses, economies, etc. going down due to blind data fallacy.

What mistakes do data scientists most often do?

There has been significant academic writing on the topic of ethics, looking at a large population and hypothesizing that higher standards of ethics are needed.

ESG is pushed in academia, and throughout a corporate system, generally from ruling bodies that themselves are unethical and in violation of laws.

The government is supposed to be a representative government (in the United States), and is a steward to the People. By using the structure of an institution to justify hypocrisy, doesn't that invalidate the legitimacy of the instituin itself?

When properly created laws dont fit the interests of politicians, the politicians violate the laws regularly, whether on issues of insider trading, vaccines mandates, immigration, taxes, retirement savings, or simply public service vs expecations for entitlement.

When science is clear that masks do not prevent spread of viruses that are smaller than mask filters, systems still push a non-scientific, bullying approach to force mask onto the very people that they are stewards to despite science and data to the contrary.

When free speech is a right and protected act, governed by the ultimate law of the land, how is it acceptable to any person seeking ESG, to allow censorship and cancel culture?

When insider trading is a violation of laws but federal reserve presidents and congress and senators do it regularly, there is hypocrisy and loss of legitimacy in the institutions.

When healthcare leaders receive royalty payments as incentives for directing business and prescriptions, doesn't it shake the foundations of transparency, ethics and conflicts of interest to the core?

If we want diversity, equity and inclusion in society, should we review sports team racial makeup, or is that untouchable? When "Black Lives Matter" is painted on basketball courts for a season, should Hispanics, Whites, Asians feel racially slurred?

Why are there "ladies night out" specials in an age that fought against gender preferences?

Why are 30% of government contracts withheld for people based on gender and race?

Hypocrisy is ruining the trust and integrity in society, but the hypocrisy comes from the top, and the most hypocritical are the ones setting policy that they themselves do not adhere to.

Is humanity on a collision course with the mirror of hypocrisy, or will institutional leadership be required to end the hypocrisy from the top?

We see hypocrisy from the top at all institutions, and the most devastating aspect is that, because of the hypocrisy at the top, a culture of hypocrisy exists throughout.

As a citizen, tax payer and white male who has been questioned and censored for using free speech, critical thinking, facts, data, science and analysis, I have legitimate concerns about the lack of integrity at the top and the hypocrisy allowed by pitically connected organizations, and the consequences of such divisive, hypocritical living and bullying leads to lack of trust, and a breakdown in society. It also weakens a society, perhaps the ultimate game plan for those living the hypocrisy.

Comments?

I am trying to join two tables using Inner join in SQL.

I am using following code:

#####################

SELECT * FROM table1

INNER JOIN table2

ON table1.a = table2.a

WHERE table1.b BETWEEN table2.b1 AND table2.b2

####################

I am getting repetition in output because table1.b is present between multiple records of table2.b1 and table2.b2

What additional code should be used to keep only the first matching record in "between" operator?

Hi all,

I am a practioner in LCA, and I am thinking how methodologies from data science, as for example data mining, machine learning, and artificial inteligence can be used in uncertainty analysis.

One possibility involves the development of simplified LCA models, based on the data, but that depends on the training datra. Does anyone have any otherr ideas?

How Machine learning and Data Science is evolving to solve industrial flow problems ???

Hi frds,

Looking for an European csv, xlsx time series regarding the daily temperature for at least the last decade.

Industry 4.0 technologies, including Big Data Analytics technology, are used in multi-criteria processing, analyzing large data sets. The technological advances taking place in the field of ICT information technology make it possible to apply analytics carried out on large sets of data on various aspects of the activities of companies, enterprises and institutions operating in different sectors and branches of the economy.

Before the development of ICT information technologies, IT tools, personal computers, etc. in the second half of the 20th century as part of the 3rd technological revolution, computerized, partially automated processing of large data sets was very difficult or impossible. As a result, building multi-criteria, multi-article, big data and information models of complex structures, simulation models, forecasting models was limited or impossible. However, the technological advances made in the current fourth technological revolution and the development of Industry 4.0 technology have changed a lot in this regard. More and more companies and enterprises are building computerized systems that allow the creation of multi-criteria simulation models within the framework of so-called digital twins, which can present, for example, computerized models that present the operation of economic processes, production processes, which are counterparts of the real processes taking place in the enterprise. An additional advantage of this type of solution is the ability to create simulations and study the changes of processes fictitiously realized in the model after the application of certain impact factors and/or activation, materialization of certain categories of risks. When large sets of historical quantitative data presenting changes in specific factors over time are added to the built multi-criteria simulation models within the framework of digital twins, it is possible to create complex multi-criteria forecasting models presenting potential scenarios for the development of specific processes in the future. Complex multi-criteria processes for which such forecasting models based on computerized digital twins can be built include climatic, natural, social, economic, pandemic, etc. processes, which can be analyzed as the environment of operating specific companies, enterprises and institutions.

In view of the above, I address the following question to the esteemed community of researchers and scientists:

What is your opinion on this issue?

Please answer,

I invite everyone to join the discussion,

Thank you very much,

Best wishes,

Dariusz Prokopowicz

Model explainability is a priority in today's data science community. Many methods emerge to extract concise logic from the black-box models. For instance, SHAP is a model-agnostic method which evaluate average marginal contribution of a feature value over all possible coalitions via shapely value. LIME builds sparse linear models around each prediction to explain how the black box model works in that local vicinity... There are other methods to explain the machine learning model. What are the pros and cons of each method? Are there any tutorials or comparison of such methods? Are there any problems to be solved in the future? :)

I have i have I havea dataset likethat :

users T1 T2 … Tn

1 [1,2,1.5] [1,3,3] … [2,2,6]

2 [1,5,1.5] [1,3,4] … [2,8,6]

.

n [1,5,7.5] [5,3,4] … [2,9,6]

Given that lists are distinct incident change by time.

My aim to find distinct incidents which might happen to users by time.

I thought of feeding the full dataset to clustering algorithms , but I need an advice from you about best algorithms to fit such 2D dataset or best approach to follow in solving this problem

Hi hi hello:)

I am looking for research topic for my final project which should be a combination of social sciences and data science (Maybe some natural language processing?). I’m studying big data management, I know python, mySQL, web scraping. My professor is interested in OSINT tools/Kali Linux. I think that Maltego and Maltego-like tools are cool but I don’t know what to analyze exactly:( Do you have any ideas? I’m also very interested in archaeological databases, especially ancient Egypt..

Thank you for your ideas

Hi,

I'm developing a Deep Q learning Model in my research.

Is it recommended to use LSTM in Deep Q learning model rather than using ANN ?

what points should i consider to select data science research topics as well.

I done my 4 year BS in mathematics.

Now i enrolled in Master in Data science.

I am new with this field guide me for research in my degree. Tell the popular areas of data science where i can research where my previous degree help me?? .

how to find problem of that area what approach for solution in general.

Hello,

I am creating a proposal for my MSc Dissertation. My research area will be data science and the topic is student attention tools for online classes based on machine learning. I am just wondering under which category my research could be categorized. Is that a quantitative one or a qualitative one?

I am really thank-full for your feedback

Hello all,

currently I'm studying Business Informatics and next month I'm going to start writing my Masterthesis. For this reason, I am searching for a topic that I can do well within the framework of my thesis. I have done a bit of research on this and still haven't found anything. However, one topic that has been on my mind for a long time is: Potential and Challenges of Citizen Development. Unfortunately, however, there is not enough literature on this topic, so there is always the fear of whether the topic is suitable for a Master's thesis. Accordingly, I would like to ask you first what you think about this topic and whether it is possible to narrow it down further if the topic is too general. I would also be very grateful if you could recommend some literature for me to look at.

In addition, I would be very grateful for further suggestions for topics. I am particularly interested in the topics "Digital Transformation", "Data Science" or "Process Management". However, since these topics are broad, can you suggest me a specific topic in this context.

Thank you in advance.

Best regards

At a time when statistics is at the core of data science, this is done without any explanation.

Well,

I am a very curious person. During Covid-19 in 2020, I through coded data and taking only the last name, noticed in my country that people with certain surnames were more likely to die than others (and this pattern has remained unchanged over time). Through mathematical ratio and proportion, inconsistencies were found by performing a "conversion" so that all surnames had the same weighting. The rest, simple exercise of probability and statistics revealed this controversial fact.

Of course, what I did was a shallow study, just a data mining exercise, but it has been something that caught my attention, even more so when talking to an Indian researcher who found similar patterns within his country about another disease.

In the context of pandemics (for the end of these and others that may come)

I think it would be interesting to have a line of research involving different professionals such as data scientists; statisticians/mathematicians; sociology and demographics; human sciences; biological sciences to compose a more refined study on this premise.

Some questions still remain:

What if we could have such answers? How should Research Ethics be handled? Could we warn people about care? How would people with certain last names considered at risk react? And the other way around? From a sociological point of view, could such a recommendation divide society into "superior" or "inferior" genes?

What do you think about it?

=================================

Note: Due to important personal matters I have taken a break and returned with my activities today, February 13, 2023. I am too happy to come across many interesting feedbacks.

Imbalanced dataset is a common problem in data science; however some approaches have been used on the dataset such as over and undersampling methods as well as boosting algorithm (for traditional machine learning approach) like adaboost. But is there any deep learning framework that will not be bias with imbalanced dataset?

I am currently undertaking a computer science MSc and have been trying to find topics of study for the my final research dissertation which would be interesting for me and I am struggling and am looking for right directions.

My interests through work are mainly cloud computing (Azure, AWS) and Data science. I am really struggling to find a topic in any of these two domains.

Any suggestions and topics related my interested domains are greatly appreciated.

Currently, data is available in forms of text, images, audio, video and other such forms.

We are able to use mathematical and statistical modeling for identifying different patterns and trends in data which can be used through machine learning which is a A.I's subsidiary for performing different decision making tasks. The data can be visualized in variety of forms for different purposes.

Data Science is currently the ultimate state of Computing. For generating data we have hardware, software, algorithms, programming, and communication channels.

But, what could be next beyond this mere data creation and manipulation in Computing?

Hi!

I'm currently working on a Data Science project for optimizing the prices of the products one of the biggest supermarket chains in Mexico.

One of the things that we are working on, is finding the price elasticity of demand of such products. What we usually do, is that, apart from fitting an XGBoost model for predicting sales, we fit a linear regression, and we get the elasticity from the coefficient corresponding to the price (the slope).

However, it is abvious that linear regression is sometimes a poor fit for the data, not to mention that the execution times are way longer since it requires to run separately XGBoost and LR (which is not good considering that there are thousands of products to model).

Because of this, it ocurred to me that we could use numerical differentiation for finding the price elasticity. At last, calculating a numerical derivative is way faster than fitting another model.

However, I'm not sure if this is mathematically correct, since the data does not come from a function.

So the question would be, is this mathematically correct? Does it make sense?

Dear statistic experts

I am developing a model to predict the behavior of around 30000 data. I use 2 different approaches to calculate the R2 and each one gives a completely different value.

The first approach: R2 = SSR/SST = 0.95

Whereas the second approach: R2=1-SSE/SST= 0.00

where SSR is Sum Square Regressions, SST is the Sum Squared Total, and SSE is Sum Squared Errors.

Any comment is highly appreciated.

Cheers,

Bahman
