Generalized Dirichlet-process-means for f-separable distortion measures

چکیده
DP-means clustering was obtained as an extension of $K$-means clustering. While it is implemented with a simple and efficient algorithm, can estimate the number clusters simultaneously. However, specifically designed for average distortion measure. Therefore, vulnerable to outliers in data, cause large maximum clusters. In this work, we extend objective function $f$-separable measures propose unified learning algorithm overcome above problems by selecting $f$. Further, influence estimated cluster center analyzed evaluate robustness against outliers. We demonstrate performance generalized method numerical experiments using real datasets.

Generalized Gamma Convolutions, Dirichlet means, Thorin measures, with explicit examples
• In Section 1, we present a number of classical results concerning the Generalized Gamma Convolution ( : GGC) variables, their Wiener-Gamma representations, and relation with the Dirichlet processes. • To a GGC variable, one may associate a unique Thorin measure. Let G a positive r.v. and Γt(G) ( resp. Γt(1/G) ) the Generalized Gamma Convolution with Thorin measure t-times the law of G (resp. ...

متن کاملDirichlet Process Mixtures of Generalized Linear Models
We propose Dirichlet Process mixtures of Generalized Linear Models (DP-GLM), a new class of methods for nonparametric regression. Given a data set of input-response pairs, the DP-GLM produces a global model of the joint distribution through a mixture of local generalized linear models. DP-GLMs allow both continuous and categorical inputs, and can model the same class of responses that can be mo...
متن کاملGeneralized spatial Dirichlet process models BY JASON
Many models for the study of point-referenced data explicitly introduce spatial random effects to capture residual spatial association. These spatial effects are customarily modelled as a zeromean stationary Gaussian process. The spatial Dirichlet process introduced by Gelfand et al. (2005) produces a random spatial process which is neither Gaussian nor stationary. Rather, it varies about a pro...
متن کاملDirichlet Process Mixtures of Generalized Mallows Models
We present a Dirichlet process mixture model over discrete incomplete rankings and study two Gibbs sampling inference techniques for estimating posterior clusterings. The first approach uses a slice sampling subcomponent for estimating cluster parameters. The second approach marginalizes out several cluster parameters by taking advantage of approximations to the conditional posteriors. We empir...
