Abstract (in Japanese) (See Japanese page) 
(in English) Constellation is an essential technique for gaining knowledge from large amounts of high-dimensional data and understanding data structure. In this paper, we propose a constellation method focusing on time-series data observed over multiple periods. If we apply SNE, which is one of the commonly used methods,
to the time series data each time, the result cannot correctly represent the change of the time series structure. In this paper, we formulate the problem as a smoothing of probability distributions on a model manifold and show that it can represent changes in time series data structure. We also propose a method to represent the addition and loss of data due to the time series change, which existing methods cannot represent.
