Becoming a data scientist requires a combination of skills in several areas, including statistics, programming, machine learning, and domain expertise in a particular field. Here is a roadmap to becoming a data scientist:

Becoming a data scientist is a lifelong learning journey, but by following this roadmap, you can build the foundation for a successful career in this exciting field.

Classifying malware using XML logs might be an interesting project that combines some of your skills and interests. I did something like this in a class project a few years back, and it was a good opportunity to show off some natural language processing as well as play around with supervised learning algorithms and even semi-supervised learning.

Here is the Kaggle competition for the class I took:

However, I am sure that malware has advanced considerably since then, so you can probably look into more up-to-date forms of malware if you find this topic of interest.

Hi.,

If you have completion tracking enabled and set up for all of the relevant activities, the Completion Progress or Completion Progress blocks will provide a "report" of all participants (including faculty) of whether or not they have completed certain activities according to the completion criteria. Or, you can simply look at their logs as the Administrator and print out the entire page of their activity.

It depends what kind of activity you are wanting to know. The logs will provide global activity (some of which will be irrelevant) whereas Completion Progress assumes that the courses/activities are set up to record (and thus be able to display) this specific course activity.

With either of these blocks, faculty can see all of the activity at a glance without any special report or MySQL queries needed.

Dear, you can search different case studies and problem and implement in phpmyadmin with sql and you must search out other problems.

live practicals labs you can access live php script with sql easily live google

Hi Félicie Dhellemmes! Would something like the Open Science Framework work for what you want? It is super easy to use and creates a DOI if you need one. https://osf.io/

In case you need.

Hello

Better you uninstall and again install the WAMP server

please see this link below, its help ful

https://help.anylogic.com/index.jsp?topic=%2Fcom.anylogic.help%2Fhtml%2Fconnectivity%2FConnecting+to+a+Database.html

A general practice is to store images in directories on the file system and store references to the images in the database. Or , you may store images on a content delivery network or numerous hosts across some great expanse of physical territory, and store references to access those resources in the database.

F1 score, Overall Accuracy or Producer Accuracy are common metrics to compare accuracy of algorithms

Hello

you can check following link, might help.

Plotly is D3 based so take a look here;

Or here;

You also can parse your json to javascript object, like here;

You can use D3 (https://d3js.org/). It is a javascript library for graphs. However, for real-time applications, I believe that you need use AJAX.

you could update a table in MATLAB using vectorization.

Colleague here is what you need.

regards.

If you directly bind the statements with front end, it will work.

You can avoid the SQL Injection by implementing Procedures.

It depends on what you want to achieve, and what the purpose of the database is. There are loads of options vfront being one of them, php maker being another. It all depends on what you want to do.

Thanks a lot  @Alaa

I am now thinking about jqplot for visualization, see examples at http://www.jqplot.com/examples/ (I like the ability of zooming). As far as launching in parallel is concerned, "make --jobs=N" is helpful because it automatically ensures that you do not lock the computer by running too many tasks at the same time.

In phpMyAdmin there is visual tool called "Designer" - you can see all the tables inside the database and relations between the tables - primary and foreign keys

Pardon, answered in wrong question :)

I didn't get your question Dinesh, could you please elaborate more?

What about hosting your data through ArcGIS Online? https://www.arcgis.com/features/

What type of error are you getting?

I use SQL commands (in MySQL, phpMyAdmin - part of XAMPP environment) for most of the problems and export CSV files to be processed by R, if is needed (diagrams etc.). But I work with SQL from 15 years. I TRUST in MySQL commands, than in R packages, because I use it more, and I can control faster. I use also R to decompose CSV files to upload into MySQL

The error is due to permissions during installation

I see here two possible directions of discussion: the hardware aspects of designing the network to be able to send data wireless underwater - which poses significant challenges by itself - and the distinct problem of writing the necessary pieces of software in order to collect the data. Please give more details in regard to your specific problem and I'll try to help you.

Not sure whether this is helpful or not.

How about

SELECT col1.number, col2.number FROM col1 LEFT JOIN col1 col2 ON col1.number<>col2.number

Netbeans and Intellij for me are the best.

To communicate with mysql you can use Servlet on the tomcat.

To communicate with java servlet you can use JSON, or have a look at some frameworks like primefaces.

This is probably too late but if you look here:

you might find the information you are looking for.

Vipul,

Please share your experiences with the several tools that have been suggested.   We would like to know your outcomes!

Dear Mr Brian, reading the chapter #16 in the Geneious Manual you can find how to setup shared databases.

Basically you must install a database manager (personally I prefer MySQL), this is a fairly simple task. Then the software will allow you to indicate that you want to use that database and create the conditions for further operation. In theory it is a fairly simple process, in practice should be too.

Reading chapter #16 and the basics from MySQL manual, Mr Alex has managed to solve this problem.

Best regards.

I am sorry to ask but please explore you question bit more. What do you mean by open layer here ?

Dear Mr Partha, I suggest to take a look at some professional ETL tool, maybe Pentaho Data Integration. You can perform parallel transformations or jobs.

Best regards.

Have you tried anything in particular?

For starters you are going to have to use the SQL server driver, and install it if you don't have it yet. More info on this StackOverflow question(see bellow).

After that you are going to have to switch between the two database drivers. You can find more info for that in the CI documentation(2nd link)

REPLACE should do the trick: http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_replace

If you got a table 'MyTable' with a column 'MyName' then the SQL statement would be:

Try this:

SELECT

  a.order_number,

  Min(a.t_calc_time) start,

  Max(a.t_calc_time) end,

  Timediff(MAX(a.t_calc_time), Min(a.t_calc_time)) time_difference

FROM

  ankit AS a

GROUP BY

  a.order_number;

It should work better and faster.

Try to limit the query for, say, a 100 records with LIMIT 0, 100 (at the end of the query) to see if the results are good?.

You can compute the sums separately e.g. via views and then assemble them in the result:

create view col1(Symbol,sum1)

as select Symbol, count(distinct Order_number)

from cash_order

group by Symbol;

create view col2(Symbol,sum2)

as select Symbol, count(distinct Order_number)

from cash_order

where Algo_Indicator=0

group by Symbol;

create view col3(Symbol,sum3)

as select Symbol, count(distinct Order_number)

from cash_order

where Algo_Indicator=0 and Market_Order_Flag='Y'

group by Symbol;

select Symbol,sum1,sum2,sum3

from (col1 natural join col2) natural join col3

order by sum1 desc into outfile '/tmp/exe4.csv';

Cf. count(distinct Order_number) assumes the one you declared in the schema is really the primary key of the relation.

First, try to optimize your table's schema according to comments and suggested changes in this fiddle http://sqlfiddle.com/#!2/9bd7c/1/0 I've made for you.

Could it be that there is more than one record with the SAME combination of order_number, buy_sell_indicator and symbol in your CSV? I guess that the order number should be unique, but you should make sure that this is not the reason for failure.

Also, it says that there are warnings. Could you list some of the warnings in the SQL error log for me to see. Maybe there is some info that could help us find the problem.

The actual complexity depend on DBMS realization. However, I do not think it is O(Log N). This formula is correct for searching for one line in a table. First, the DBMS selects lines from a table, then it counts them. Number of the selected is equal to the number of  occurrences which is 0..N. If there are 0 or 1 occurrences then the complexity is O(Log N). After finding the first occurrence, the algorithm must check if there are more occurrences. In a tree, this operation is performed in a single step. But algorithm must repeat this single step at least as many times as many occurrences. If there are more than 1 ones, it is probably O(M + log N) where M is quantity of occurrences or less than this value but more than O(log N). If M is small (in comparison with N) then the complexity is O(log N).

Hi Debasish, great work.

I also working in something similar using mysql, my goal is a protein folding prediction, but Im still in the very beginning and I'm still learning about biochemistry but maybe we can share some info about mysql.

QGIS is a nice platform for various formats, as it uses GDAL and other tools to make data usable. OSM can be accessed in QGIS directly as a raster, via a supplied plugin, and you can use all sorts of vectors on top of it.

I like QGIS because it manages various exotic projections seamlessly, and I need it for that particular reason. It also supports other open maps, and WMS online sources.

If you are new to QGIS, go for a 32 bit version, and install Python first.

Netbeans and Eclipse are open source. PhpStorm from jetbrains is a great idea but is paid.

MySQL is controlled by it self, as you know its a DBMS.

PHP is just used to retrieve data from MySQL database. Therefore, I think you should look for the MySQL DBMS optimization.

What type of data it is? What do you mean by processing 12M data at a time? If your database has 12M entries and you want to update and retrieve data, then you need to improve your searching algorithm in your PHP script. However, this will improve the performance of the program, not the MySQL database.

These are my 2 cents.

Good luck,

Sarves

Thanks Johannes.

I would like to add (it just came up to my mind) that another possible option (since there is the necessity to deal with relationships) might be to resort to a graph database: for example HyperGraphDB (http://www.hypergraphdb.org/index)
