I agree on avoiding a flat namespace, but I disagree on doing it as
Matthieu suggested: where does classification starts, where does
clustering ends, where does pdf estimation goes in between ? You can use
EM or SVM to do similar things (discriminative classification,
clustering). For example, I have almost ready examples to do clustering,
pdf estimation and discrimative learning: the actual implementation is
the same, EM. The usage is different.
I prefer to keep the "implementation concept" and the "usage concept"
separate at the namespace level. That is I agree that having a
classification or clustering namespace is useulf, but not to separate
svm or em. I may miss your argument, though ?
