Weberative mixture-model approach to clustering directionaldata based on the von Mises-Fisher (vMF) distribution, which arises naturally for data distributed on the unit hypersphere. In particular, we derive and analyze two variants of the Expectation Maximization (EM) framework for estimating the mean and concentration parameters of this mixture.

WebFisher distribution is a compact form of an exponential density model developed for random matrices, and the properties of the matrix Fisher distributions have been studied in di-rectional statistics [11], [12]. When applied to the special orthogonal group, the matrix Fisher distribution is deﬁned by Web1 Neyman-Fisher Factorization Theorem Theorem 2. The statistic T is suﬃcient for θ if and only if functions g and h can be found such that f X(x θ) = h(x)g(θ,T(x)) (2) 1. The central idea in proving this theorem can be found in the case of discrete random variables. Proof. Because T is a function of x,

WebThe von Mises-Fisher distribution (vMF;Mardia & Jupp, 2009) is a natural and standard choice for densities in hyper-spheres. It is a two-parameter exponential family, one pa-rameter being a mean direction and the other a scalar con-centration, and it is symmetric about the former. Because
