| Abstract(in English) | In this paper, we propose a novel framework for estimating state spaces where the size is unknown. The proposed framework resolves rapid transitions among redundant states, which are common problem with nonparametric state estimation models. Our approach is based on segmentation and segment categorization, while another approach is sticky extension (Fox et al., 2008). We provide an inference strategy for hidden Markov model and switching linear dynamical system. By using synthetic data and motion capture data, we demonstrate that our method is superior over conventional methods in view of extracting motion sequences and inference efficiency. |
