| Abstract(in English) | In this paper, we propose a change detection method on temporal variation of subspace geometry. In the proposed method, temporal variation of time series data is observed by multiple canonical angles obtained by two state subspaces at time $t$ and $t+ Delta t$. Using artificially generated datasets and real-world datasets, we evaluate the effectiveness of the proposed method over the conventional methods. |
