I am doing control flow and data flow analysis to my examle code. I am using instant analyzer (Analyzer with code fix - Nuget,VSIX)
My aim is analyze not only the code developer coding, also want to follow the data to the other classes.
Can i learn your thoughts about that ?
Thanks

I have received a legacy code from my company's previous project without any document and description left. The only part of these code I can recognize is Jetty for API. I can't even find the database it use yet 😛
Miserably, I probably need to do some modification of this system.
Is there a way&tools for figuring the component and relationship of this system? I mean like modeling a causal loop diagram or something by monitoring data interaction through running process and IPC etc.
I have used some previous knowledge of regular website forming langue (HTML) to locate particular syntax of code for modification.
but there should be a more general mythology and tools for analyzing the dynamic of cooperating process.
I am trying to implement a system to prevent discrimination in data mining using the preprocessing technique, using the Adult Dataset. So far, I have preprocessed the data and extracted the frequent classification rules. But am unable to go forward with calculating the elift, elb values for the rules, which is a major step. My work is based on the paper "Methodology for direct and indirect discrimination prevention in data mining". So if anyone could help me out with this, it would be really great.
I feel helpless especially without proper documentation for WSDL2C codegen tool. Here is the question with little background:
I was able to download the WSO2-WSF-C-SRC (C source) and able to compile and get the SOAP server running. Also created a wsdl file and generated server skeleton code using WSDL2C codegen tool. The codegen code is way bigger than the code that appears in the Samples provided in the download. Unfortunately, there isn't much literature for the code generated by the WSDL2C tool. Can someone help as to how the start my business logic coding? How to set some default values to all the output parameters? I was able to figure out the location to start. I wish there is a sample code somewhere with the business logic code as well. Can someone help?
Thanks in advance.
Well, I cracked the code. Obviously, one has to go through the code to understand the basic structure, which I did, finally.
Best Wishes.
I have two apps that need to receive notifications when data in a table changes. One .NET and the other C++ MFC. I decided to go with SQL Query Notifications.
I have built a proof of concept for the .NET app with SqlDependency class, but am struggling with the MFC version.
I found this http://msdn.microsoft.com/en-us/library/ms130764.aspx, but am not proficient enough with c++ to make sense of this.
Has anyone done this before? If so, could you please post some sample code or point me in the right direction?
Thanks in Advance
I can't see example code for C++ anywhere.
Rather than write and debug this (complex) event detection code twice, it would be possible (and preferable imo) to implement it in C#, and then expose the required function to your MFC app via COM interop. See here for a brief overview.
I have recently become interested in the field(s) of data mining and machine learning. The idea of going through huge datasets and trying to correlate hidden patterns and trends is fascinating. So far I have done the following
Used Weka to load simple data sets and generate decision trees
Continously read books, wiki's, blogs and SO on the same
Started playing around SQL Server DM and Python API's
Have an idea on options of freely available data sets on the web(freedb, UN etc)
What is hindering me is the minute I try to go beyond classification/associsciation and into priori/apriori algorithms I am stuck because understanding mathematical equations and logic is not(to put it modestly) one of my strong points.
So my question would be are there anybody in the Data mining field(in the role of product owner or builder) who are not naturally mathematicians? If so, how would you approach in undestanding the field since free tools like Weka and Rapid-miner both expects some mathematical/statistical background?
P.S: Excuse me if I made some mistake in the query like mixing Data mining and analytics when they are separate as I am still getting my feet wet. I hope my core question is clear.
Well, being able to do some analysis of what the data mining models are showing is absolutely vital. However, these days all of the math and statistics are taken care of by the data mining models. You don't need to understand the math behind them (although it helps).
For example, you can look through the SQL Server Analysis Services Data Mining Algorithms and see that even the technical reference is how to use these implementations, not how to recreate them.
If you can understand the business cases and you can understand what the data mining is telling you, there's really no need to delve into the math behind it.
As for some of the free tools, I've never used them, so I can't speak to them. However, I'm a big fan of SSAS and those data mining models, which don't require an extensive mathematical background.
As Eric says, and as far as you only intend to use the existing algorithms and APIs and make sense from them, I don't see problems with the required math/statistics skill set (anyway, you'll need some previous basic knowledge/level).
Now, if you intend to do research or if you want to improve or modify existing algorithms, or why not, create your own algorithms, then math and statistics is a MUST. I just started doing some research in this area, and I'm still trying to fill my skills gap =)
