概率原型分析软件，语言matlab，属于数据分析软件，非监督学习方法，类似于PCA,NMF等-Archetypal analysis represents a set of observations as convex combinations of pure patterns, or archetypes.
The original geometric formulation of finding archetypes by approximating the convex hull of the observations assumes them to be real valued. This, unfortunately, is not compatible with many practical situations.
In this paper we revisit archetypal analysis the basic principles, and propose a probabilistic fr a mework that accommodates other observation types such as integers, binary, and probability vectors. We
corroborate the proposed methodology with convincing real-world applications on finding archetypal winter tourists based on binary survey data, archetypal disaster-affected countries based on disaster count data,
and document archetypes based on term-frequency data. We also present an appropriate visualization tool
to summarize archetypal analysis solution better.
