Probabilistic topic models, as represented by latent Dirichlet allocation (LDA), have been widely used for analyzing not only categorical but also continuous data such as times of word appearance and price information. In the topic model for continuous data, however, the component distributions needs to be simple exponential families like normal distributions to perform the efficient parameter estimation, which limits the representative power of the model. In this paper, by incorporating the nonparametric histogram density estimator into the topic model, we construct a new probabilistic topic model to overcome the limitation. The estimation of the parameters, including the bin width selection, is performed by using efficient collapsed Gibbs sampling. We derive the estimation algorithms for the regular and variable bin width scenarios. We apply the proposed method to synthetic data, confirming that it performs well. |
