Variational Learning for the Inverted Beta-Liouville Mixture Model and Its Application to Text Categorization
The 15-eg1053cl finite invert Beta-Liouville mixture model (IBLMM) has recently gained some attention due to its positive data modeling capability.Under the conventional variational inference (VI) framework, the analytically tractable solution to the optimization of the variational posterior distribution cannot be obtained, since the variational ob
