New C++ library libhmm offers accurate HMM parameter estimation

A new C++20 library called libhmm has been developed for Hidden Markov Models (HMMs), addressing a lack of well-maintained, embeddable C++ HMM software. It corrects the common use of approximations in the Baum-Welch algorithm's emission distribution M-step by implementing accurate maximum likelihood estimators for various continuous and discrete distributions. The library also features log-space calculations for forward-backward and Viterbi algorithms, SIMD acceleration, and Python bindings, with performance validated against existing libraries and R packages.

    libhmm: A Modern C++20 Library for Hidden Markov Models with Correct MLE Emission M-Steps

    arXiv:2605.29208v1 Announce Type: cross Abstract: We describe libhmm, a C++20 library for Hidden Markov Model parameter estimation, sequence decoding, and model selection. libhmm addresses two gaps in existing software: the absence of a well-maintained, zero-dependency C++ HMM li…
