Latent IBP Compound Dirichlet Allocation [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2015 We introduce the four-parameter IBP compound Dirichlet process (ICDP), a stochastic process that generates sparse non-negative vectors with potentially an unbounded number of entries. If we repeatedly sample from the ICDP we can generate sparse matrices with an infinite number of columns and power-law characteristics.

Inference in Supervised latent Dirichlet allocation [PDF]
2011 IEEE International Workshop on Machine Learning for Signal Processing, 2011 Supervised latent Dirichlet allocation (Supervised-LDA) [1] is a probabilistic topic model that can be used for classification. One of the advantages of Supervised-LDA over unsupervised LDA is that it can potentially learn topics that are inline with the class label.
