We propose a new probabilistic model to analyze time-varying relational data such as e-mail transaction profiles. Our model can extract patterns or features underlying on the dynamic relational data, and capture their evolution by introducing a latent variable on the low-dimensional feature space. We derive a learning procedure based on EM algorithm. In particular, E-step is approximated by expectation propagation. In the experiments using both artificial and real-world datasets, we demonstrate our method can appropriately estimate the structure of temporally changing relations and effectively predict them. |
