Abstract
The information processing apparatus () of the example embodiment 1 includes an acquisition unit (), a clustering unit (), and a modeling unit (). The acquisition unit () acquires a plurality of trajectory data. Until a predetermined termination condition is satisfied, the clustering unit () repeatedly performs: 1) dividing the plurality of trajectory data into one or more groups using a group identity distribution of each trajectory data; 2) determining a time-sequence of representative velocity for each group; 3) determining, for each trajectory data, a time-sequence of a latent position distribution of a corresponding object; and 4) determining a scaling factor for each trajectory data; and 5) updating the group identity distribution of each trajectory data. The modeling unit () generates a model data for each group. The model data includes the time-sequence of representative velocity generated by the clustering unit ().
