Abstract(in Japanese) (See Japanese page)
Abstract(in English) Probabilistic Latent Semantic Analysis and Latent Dirichlet analysis are known as topic models to analyze text data and images. When parameters (= solution) of the topic model are obtained by the optimization algorithm, various solutions are reached due to differences in algorithms, initial values. In order to select a solution from various solutions according to the purpose of use, it is necessary to know what kind of solutions exist. This report presents previous proposals for analyzing diverse solutions and obtaining an overall picture of the solutions and indicates issues to be addressed.
