Abstract
The information processing apparatus () of the example embodiment 1 includes an acquisition unit (), a clustering unit (), a transformation unit () and modeling unit (). Until a predetermined termination condition is determined, the clustering unit () repeatedly preforms: 1) optimizing the posterior parameters for clustering assignment for each data streams; 2) optimizes the posterior parameters for each determined cluster and for each time frame; 3) optimizes the posterior parameters for individual responses for each data stream; 4) optimizes the posterior parameters for latent states, via approximating the observation model through non-conjugate inference. The transformation unit () transforms the latent states into parameters of the observation model, through a transformation function. The modeling unit () generates the model data, which including all the optimized parameters of all the model latent variables, optimized inside the clustering unit ().
