Abstract(in English) | A Topic model is known as a useful statistical model for analyzing text data and images. Many different parameters (solutions) of a topic model can be obtained due to different initial conditions. To utilize diversity of solutions, we proposed the method to assign coordinate values to the solutions by defining inner product (similarity) between solutions, where inner product is normalized mutual information between them. Through the experiment for one document data set, usefulness of the proposed analysis method had been shown. In this report, we apply it to various document data and analyze it, and show the experimental results and investigate them. |
