learn attribute vector based on the relation and difference between different categories (each dimension if uninterpretable): [1] (Laplacian matrix), [2] (triplet loss)
exploit local information and encode them into attribute vector (each dimension is interpretable): [3] (discriminative cluster, doublets), [4] (joint attribute learning and feature learning)
learn attention map for each latent attribute [5]
