    Modeling climate variables using Bayesian finite mixture models
    (2015-05) Cuthbertson, Thomas Edwin; Keitt, Timothy H.; Müller, Peter
    This paper presents an alternative to point-based clustering models using a Bayesian finite mixture model. Using a simulation of soil moisture data in the Amazon region of South America, a Bayesian mixture of regressions is used to preserve periodic behavior within clusters. The mixture model provides a full probabilistic description of all uncertainties in the parameters that generated the data in addition to a clustering algorithm which better preserves the periodic nature of data at a particular pixel.
