- Afaq Ahmad added an answer:29Are PhD/Masters Theses and Dissertations or Journals/Conference proceedings the best sources for a Literature Review? Why?When reviewing the literature for trends in technological advancement and future directions, we may use either PhD and Masters' theses and dissertations. But which will be useful, or give the most rigorous review?
Dear John K. Marco Pima
PhD, Masters: Theses and Dissertations provide us a quick access to methodologies and tools along with scope of future works. Since these documents are quickly available for research groups at same institute. Hence, referring these are essential if research idea/methodology/tool/comparison benchmark is used.
Since Theses and Dissertations are not accessible or publicized immediately therefore, it is not commonly referred by other researchers of the same field. Because most of the the research papers are from the Theses' and Dissertations' work, so generally, referring of these are not prime issue.
Conference papers are commonly discusses new ideas, tools, methodologies, technologies and comments but not to the extents of completeness. Some good conferences adhere a standard like IEEExplore. Standard conference papers and /or conference papers designed from same research groups / fields are justified for referencing.
Standard journal papers are the best source of breakthrough of your research and make a practice of it and therefore, this the best source of reference.Following

- Remy Fannader added an answer:7Is it possible to explain the operational/tactical/strategic classification in terms of real-time KM ?
The basic idea is to use events and the processing of associated data to bridge the gap between operational and decision-making systems.
I will assume that internal events are meant to be managed, which means that risks are by definition external. Then I will use the classic distinction:
Operational: full information on external state of affairs allows for immediate appraisal of prospective states.
Tactical: partially defined external state of affairs allow for periodic appraisal of prospective states in synch with production cycles.
Strategic: undefined defined external state of affairs don’t allow for periodic appraisal of prospective states in synch with production cycles; their definition may also be affected through feedback.Following
- Ibrahim Abubakar added an answer:4How do you classify documents using WEKA?
Please I need help on how to go about classifying documents using WEKA. I am doing classification of dissertations of my department. The assignment is to do an Ontology-based classification of 250 dissertations against Gartner's Hype cycle. The aim is to determine which field of IT each dissertation falls into.
thank you. It really helps. I will try using some of the suggested classifiers.
- Marc Scheibel added an answer:6Can anyone help to determine the time lag between flood gauges from upstream to downstream?Can anyone suggest how we should calculate time lags of historical flow data between upstream and downstream gauges for urban flood prediction (considering that for various flood events the time lags between upstream and downstream flow stations can change depends on precipitation characteristics and and hydrologic condition of catchments)?
There are flood routing methods like Muskingum and Kalinin-Milijukov, in which you can estimate the translation and the retention effects in the river section.Following
- Ian Kennedy added an answer:3Domain specific search?I have been guiding research scholars in the area of Domain Specific Ontology Searching Techniques. If any one would like to share your expertise with published papers, I will really appreciate that.

- Dr. Indrajit Mandal added an answer:1Is there any way to do manual prunning over the result (decision trees) of a trained Random Forest Model?
The idea is to do an online pruning using a continuous timestamped dataset...and I wanted to train my model using some data then improve it during the day with some other information that I may receive (i.e. active learning, weather condition, etc.). It could be by prunning (i.e. removing some tree brunches) or by adding more branches to the current leaves. Are there any R packages that support such an implementation? Which would be the best way to do so? Thank you in advance.
Yes its possible .
if the dataset contains less number of attributes.
else it may become highly tedious job.

- Sanjay Garg added an answer:2Is OOB error rate always random?
Bootstrapped sample and a tree built using the same. Why is it that OOB error estimate a random value?
OOB predictions are based on a small subsample of the trees in the forest and are thus at a disadvantage relative to predictions that can be legitimately based on the entire forest.
OOB predictions are not expected to exhibit better performance because their distribution is not the same as the distribution on which the individual trees are grown
Advantage of randomness is obviously to get better ensemble.following article may help you in this regard
- Johan A.K. Suykens added an answer:9How can I classify data with missing values using conventional classifiers?
The tolerance rough set model is a perfect model that deal with missing values in the data sets. But how can I use the tolerance rough set model to classify data using the conventional classifier as KNN?
In the context of support vector machines it is possible to also change the problem formulation in the case of missing values, see e.g.

- Eldar Sultanow added an answer:8Why knowledge is not highly valued as a decisive element to sustain competitive organizational position?I drew your attention to 5 organizational elements as presented by D. McFarland from Stanford University in his Organizational Analysis MOOC Class. Technology, Participants, Goals, Social Structure, and Environment. Drucker cosiders knowledge as the primary resource, and land, labor, and capital as secondary resources. General categorization are physical, social and technical.
Our study has shown, that on the management level of organizations, knowledge (especially epistemologically progressed knowledge that is decision relevant) is valued very high. This applies not to the operational level of organizations.
Another phenomenon is, that the more knowledge is tacit and bound to persons, the more it has been highly valued.Following
- Tarik A. Rashid added an answer:6May I know what is the difference of global and local search in term of machine learning and computer science?Global search vs local search.
Ideally speaking, a global searching technique is promising to make sure to find the best global formation but this is achieved most ly at the cost of a long time searching. But then again in reality, they are run and stop when stopping criterion is come across. Examples of this search include, particle swarm optimization. simulated annealing, and genetic algorithm. Whereas, local search algorithms do not totally focus on search and but it attempts to move from a current formation to a neighboring refining formation. This is much depending on the initial search space and initial formation. An example of local search is hill climbing, which is an iterative algorithm which can start with a random solution and then after the algorithm tries to find a better solution by incrementally altering a solution of single element. If this alteration harvests a better solution, an incremental alteration is made to a new solution, this process can be repeated in anticipation of no more enhancement is identified.Following

- Anteneh Ayanso added an answer:4How does mathematics and statistics explain the logic behind association rules which is essential for the decision making process?
There are many different forms of mathematics. Different forms satisfies different understandings of association rules. Effectiveness and efficiency of same association rules are different in these mathematical explanations. So, how is it possible that the association rules which has many different mathematical explanetions, may support a single decision? And how can I know which of these explanations are correct and which are wrong?
The key is to use interestingness measures that explain association between items or events beyond random chance, given that these items or events co-occur at an acceptable level of frequency(aka support ). Acceptable interestingness measures include confidence, lift, conviction, etc.Following

- Emmanuel Detrinidad added an answer:15How can small and medium enterprises benefit from Big Data and Data Science?Big Data and Data Science have continued to emerge among practitioners and researchers. But the foundation of these concepts involve large volumes and a variety of data created at high velocity. Hence, the focus have generally been on bigger organisations that generate such data. However, small and medium sized organisations are also active adopter of ICT. Can Big Data and Data Science benefit small and medium enterprises as well and how?I´m not sure about the use of "big data" in the SME. I mean if they (the CME) work independently the will need data mining tools. Think that will be enough.
But if you are thinking in the coordination of a cluster of servers from a cluster of SME thats another story.Following
