The Discrete Infinite Logistic Normal Distribution for Mixed-Membership Modeling, incl. discussion by Frank Wood

Published on May 06, 20114281 Views

We present the discrete infinite logistic normal distribution (DILN, “Dylan”), a Bayesian nonparametric prior for mixed membership models. DILN is a generalization of the hierarchical Dirichlet pr
