Online variational learning of generalized Dirichlet mixture models with feature selection
Wentao Fan,Nizar Bouguila +1 more
TL;DR: A principled variational approach for learning the parameters of the proposed statistical model allows to control overfitting by, dynamically and simultaneously, adjusting the mixture model's parameters, number of components and the features weights.
Journal ArticleDOI
Variational learning for Dirichlet process mixtures of Dirichlet distributions and applications
Wentao Fan,Nizar Bouguila +1 more
TL;DR: The proposed infinite Dirichlet mixture model with variational learning requires only a modest amount of computational power which makes it suitable to large applications and is experimentally investigated through both synthetic data sets and challenging real-life multimedia applications.
Journal ArticleDOI
Efficient cross-modal retrieval via flexible supervised collective matrix factorization hashing
TL;DR: This paper proposes a flexible supervised collective matrix factorization hashing (FS-CMFH) to efficient cross-modal retrieval that performs favorably compared to the state-of-the-art competing approaches.
Journal ArticleDOI
Online variational learning of finite Dirichlet mixture models
Wentao Fan,Nizar Bouguila +1 more
TL;DR: An online variational inference algorithm for finite Dirichlet mixture models learning by adopting the variational Bayes framework in an online manner, so that all the involved parameters and the model complexity can be estimated simultaneously in a closed form.
Journal ArticleDOI
A hierarchical Dirichlet process mixture of generalized Dirichlet distributions for feature selection
TL;DR: This paper addresses the problem of identifying meaningful patterns and trends in data via clustering by developing two variational learning approaches (i.e. batch and incremental) for learning the parameters of the proposed model.
