Learning complex-valued latent filters with absolute cosine similarity
ICASSP 2017accepted
We propose a new sparse coding technique based on the power mean of phase-invariant cosine distances. Our approach is a generalization of sparse filtering and K-hyperlines clustering. It offers a better sparsity enforcer than the L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="htt…
