Hello,
I have gathered some site details where you find applets (with code very often).
These are educational applets. I can't really say which site I found code for
c4.5. But I did see in some of the following.

Binomial Distribution
Occams Razor
Principal Component Analysis Applet
Some other Nearest Neighbour rules related applets
Adaptive Principal Component Extraction
PCA From other Learning Procedures
Perceptron Learning

Hello Shehzad, I know that there is a class which implements the ID3
algorithm in the Weka framework. You can find it at
http://www.cs. waikato.ac. nz/ml/weka/
Unfortunately I don't know where you may find the C4.5

Bye bye
Emanuele

data Mining area of Classification. I search on the internet for the
code of ID3 and C 4.5 for decesion tree. Also if some one have worked
in using Swarm intelligence wiht data mining. I wasnt able to find any
working code. If any one, who have written the code or can tell me any
link, i will be very grateful.
