| Outline of Final Research Achievements |
We aim to estimate probabilistic latent structure underlying collections of text data and network data with internal structure or external structure. The internal structure indicates, for instance, the attributed word tokens in text data or attributed nodes or edges in network data. The external structure indicates, for instance, the case when each node of network data is associated with a set of text data. We extract "knowledge" that can apply for various real-world problems, by estimating low-dimensional latent structure from a large amount of complexly structured data. We apply our techniques to the problems of information retrieval, recommendation, prediction, and time-series analysis.
