CBayes Input

Hi,

I've played with the bayes 20newsgroups example, but I'd like to try
running the cbayes algorithm on it also. The example script doesn't seem to
offer this, so I dug into the code a bit and it looks like the input to
cbayes is sequence files rather than key/value text files.

Can anyone tell me how those sequence files should be formatted? I couldn't
find it documented anywhere. Also I don't suppose there's a handy prepare
data program to get it running on the 20newsgroups data easily?

Thanks,

Tom

Thanks, I just realised I was getting the wrong end of the stick - looking
at the theta normalizer driver code thinking it was the classifier driver...

Cheers!

In the command line example replace "bayes" with  "cbayes". That's all you
need to do.
