| Research Abstract |
In this research, a statistical approach of human behavior modeling is proposed and verified. In this study, issues on automatic extraction of latent factors from human behavior data are focused. In contrast to the conventional human behavior modeling where behavior models are estimated independently from each individual, the proposed model, which is formulated with Dirichlet process priors, automatically couples similar human behavior and provides robust estimation from the coupled behavior data. Empirical evaluation using human behavior sensor data shows that our model improves better estimation accuracy.
