I'm working on my final year project on ocr in opencv,i have done segmentation of the image and feature extraction,now i have to train to make it recognize the alphabet ,give me an idea of how to do that
I don't know what you have done until now and what feature set you are using. Anyway below links will be a good start.
1) Basic OCR in OpenCV - It uses k-Nearest Neighbours
2) Also try this : Simple Digit Recognition OCR in OpenCV-Python
3) OpenCV samples come with an letter-recongnition sample. Have a look at that!!
Finally, work yourself a lot on your project. Google for your doubts. If you don't find any way,
come here, tell what you have done, and now what is stopping you.

I have been trying to implement the Naive Bayes and OneR classification algorithm using SAS Enterprise Miner 7.1.
The problem is I have not been able to find a Node that I can drag onto the diagram and do that. Is there any way to implement these algorithms directly in SAS without having to write additional SAS Script?
See: http://listserv.uga.edu/cgi-bin/wa?A2=ind1202c&L=sas-l&D=0&P=2796
I don't think this is possible using a native node. The above link suggests that Rick Wicklin did write something that might help here, but it's beyond my google-fu. You might re-ask this question on the SAS-L mailing list (email to sas-l#listserv.uga.edu or find the Google Group).

this has been asked plenty of times, but I always find them hard to follow. Its quite simple.
How do you add a library and/or framework to xcode and/ or your xcode project. I need all the steps between downloading the library, to typing the #include in the code. But I also need some context behind each step, other wise it won't stick in my mind and I'll back here in a week. Bear in mind I have an limited understanding of the xcode development environment. Thanks in advance.
Follow the screenshots and you are good to go

I am reading some introduction of an ancient Chinese game called Mahjong (a bit like poker but far more complicated). I have been spending couple days in writing a program to determine if a given hand is a win hand or not. Do anyone have any idea or know where can I find the free code for that? I only need the part to determine win/lose, I am not looking for the entire project. Thanks.
There is this cool Python library that can be used for scoring of a Mahjong hand given a situation. I know you are working in C++, but since python is highly readable, even to non-python coders, maybe you'll be able to copy/paste and edit the relevant part so you'll be able to use them.
Hope that helps you in some way.

I would like to know if there is an already samples of doing data flow graphs using QT graphics API.
I would like to see some samples to get started with.
Qt comes with various examples that might help you get started.
The following two examples come to mind:
The Diagram Scene Example
Elastic Nodes Example
Have a look at those for some inspiration.
Qt-based, but a separate project which is possibly more along the lines of what you're looking for is NUKEEngine's Qt Node Editor.

I am looking at ways of creating my own DBMS from scratch in C++ (just for fun and educational purposes). I am stuck with the place to start it. Can anybody tell me how I should begin (design) this. Will postgresql code and the architecture be of any help?
Thanks in advance.
Have a look at SQLite and its doccumentation. it might be a good point to start.
Start by reading "Transaction Processing: Concepts & Techniques" by Gray and Reuter. It goes through all the major components of a DBMS. Following the references is very interesting.
It is almost 20 years old now, but still very relevant.
