Abstract

The Minimum Description Length (MDL) principle is a method for model selection that trades off between the explanation of the data by the model and the complexity of the model itself. Inspired by the MDL principle, we develop an objective function for generative models that captures the description of the data by the model (log-likelihood) and the description of the model (model size). We also develop a efficient general search algorithm based on the MAP-EM framework to optimize this function. Since recent work has shown that minimizing the model size in a Hidden
