embeddings of the training data points this method uses a bi-directional ostium and then we get a model that can do anyway classification is actually better trained for anyway classification now if you have more than one example per class what this will do is it will independently compare the test image with each of those examples per class and one of the things that might be nice to do is actually to better integrate the information across different examples for our class to aggregate cost information into a sort of prototypical
