Fast Convolutive Nonnegative Matrix Factorization Through Coordinate and Block Coordinate Updates

29 Jun 2019Anthony DeglerisBen AntinSurya GanguliAlex H Williams

Identifying recurring patterns in high-dimensional time series data is an important problem in many scientific domains. A popular model to achieve this is convolutive nonnegative matrix factorization (CNMF), which extends classic nonnegative matrix factorization (NMF) to extract short-lived temporal motifs from a long time series...
