I am using version 0.14.1 of sklearn. I have a multiple output problem. I am using the yeast dataset. The input x is a protein (103 dim vector) and the output are the different functions it performs (characteristic vector for 14 functions). So I am looking for a classifier which gives a one-zero classification for each of the 14 functions.
