Well, a classifier gives back the class to which a point belongs to, doesn't
it ? Do you mean adding probabilities ? It would depend on the kind of the
classifier (strong or fuzzy).
For the time being, David proposed a data format, at least for inputs. The
same format could be extended to output values (when it has sense).

I see. I say that it is good idea to write parsers for different data
I agree, I hope that David will be able to finish the Scons build of numpy
and scipy so that he will be able to enhance his data format proposal :)
