prototypes this is denoted as D and then perform a softmax operation to decide which class it corresponds to and in this case D can correspond to Euclidean distance or cosine distance great so this is a simple approach that works quite well and there are a couple other extensions that we can make upon it so so far we've looked at Siamese networks about two networks they're prototypical that works at all correspond to some sort of embedding in the nearest neighbors either two examples or two prototypes when tanta comes up is what if you need
