WebOnline Variational Inference for the Hierarchical Dirichlet Process can be performed by simple coordinate ascent [11]. (This is the property that allowed [7] to derive an efﬁcient online variational Bayes algorithm for LDA.) In this setting, on-line variational Bayes is signiﬁcantly faster than traditional WebThis approach has made variational inference applicable to a large class of complex generative models.
