Thread Subject: classification

I have a dataset. i like to classify this data into two
classes (class A, class B).
i devide the data into three parts: training, valdiating,
testing.
i construct trainging model and the testing algorithm i
don't have problem here. for valdition i use (PCA And SVM).
can any one give me an example how to train PCA and use it
for classification.
i know how to use (PCA/SVM) for dimension reduction.

can any one give me another idea

In general, PCA is not recommended for
classification. Search Google Groups using

Hope this helps.

thanks for your answer. i found the web site , it seems to
be about Neural Networks!. if i faced with new problems i
well return
