because here is a plus and now they minimize the entropy let's see what they say by minimizing the following objective now entropy is the sum of the negative sum of P log P and this if this is P yes this is the probability that an image is are going to be assigned to cluster C over the entire dataset so they're going to mmm yes so it's negative this quantity negative minus P log P and this is the entropy so they're going to minimize the entropy let's see what they say we include an entropy term the second term in equation two which
