Hi,

Do you want me to reformulate my problem?
Please tell me if I'm not clear enough or if my question is inappropriate (e.g. too large).

Thanks

Hi,

in Mahout examples, the (org.apache.mahout.classifier.sgd.)RunLogistic
class is a great example to classify content with SGD and to get a nice
confusion matrix.

I'm trying to use and adapt this to classify data in more than 2 categories.
The alorithm uses classify scalar methods, which is only working with 2
categories.

"classifyScalar" method in AbstractOnlineLogisticRegression class return
a double when we evaluate the model. This double is used as a score fot
the matrix.

"classify" seems to be equivalent but returns another vector, I guess
because the matrix has more than one row in that case.

I'm looking for a way to do this with more categories. Do you have a
clue or example for doing this ?

Thanks

Loic
