then basically send the image that's the image right here send the image through the deep neural network and then either take this last state right here so it goes through and through and through and we could get take either of the hidden states or we could just take you know the last state that is the sort of hidden representation right here and do the clustering with that but then of course the question is what do you what which neural network do you take how do you train that neural network and there have been a few approaches such as a
