pyrichlet: A Python Package for Density Estimation and Clustering Using Gaussian Mixture Models

open access: yesJournal of Statistical Software
Bayesian nonparametric models have proven to be successful tools for clustering and density estimation. While there exists a nourished ecosystem of implementations in R, for Python there are only a few. Here we develop a Python package called pyrichlet,

K­MEANS CLUSTERING FOR HIDDEN MARKOV MODEL

open access: yes, 2004
An unsupervised k­means clustering algorithm for hidden Markov models is described and applied to the task of generating subclass models for individual handwritten character classes. The algorithm is compared to a related clustering method and shown to give a relative change in the error rate of as much as 8% on a 30,000­word vocabulary, unconstrained­

Hidden Markov Mixtures for Change Detection in Unevenly Spaced Time Series

open access: yesAustrian Journal of Statistics
This work tackles sequential data change-point detection, a research area with various applications in different fields. It focuses on analyzing sequential data such that the distance between locations of consecutive observations is not fixed.
