I've got a matrix of feature vectors where all features are categorical.
Before I can treat these as features, they need to be binarized, as
described
here<http://scikit-learn.github.com/scikit-learn-tutorial/general_concepts.html#handling-categorical-features>
.
I have written my own function to solve this problem, but I'd rather use
one from scikit-learn that is both efficient and has been reviewed by
others. Is there any function that can do this for me? It seems like a
common problem--common enough that a function in scikit-learn should solve
it for me.
Best regards,
Conrad Lee
