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. However, there are many similar solutions,
and it is redundant to treat them as different findings. To find
non-redundant solution sets, We propose a method to calculate
normalized mutual information (NMI) as similarity (inner product)
between solutions, apply multidimensional scale method to coordinate
values to them, and enable analysis and visualization.
Distribution situation of solutions was visualized by experiment using various text data. We also clarified the dependence of representative
algorithms (maximum a posterior estimation, collapsed Gibbs sampling,
collapsed variational Bayesian inference) and initial
values, and confirmed the usefulness of the proposed method. |
