L1/2-regularized nonnegative matrix factorization for HMM-based sequence representation learning

Symbolic sequence representation plays a pivotal role in many resource-constrained expert systems. Recently, Hidden Markov Model (HMM)-based methods have received extensive interest due to their ability to capture underlying structural features with interpretability, especially for representation le...
