Two new research papers explore advancements in Hidden Markov Models (HMMs). The first paper introduces Controller-Augmented Hidden Markov Models (CHMMs) as a framework to handle pathwise constraints that violate the standard Markovian assumption, offering theoretical guarantees and empirical validation on sequence-labeling tasks. The second paper systematically evaluates different initialization strategies for Infinite Hidden Markov Models (IHMMs), finding that distance-based clustering initializations outperform common alternatives for modeling time-series with structural changes.
