  • Publication number: 20250005409
    Abstract: A storage device stores a state transition model in which a first state transition probability (state transition probability function ?), which indicates the probability that a prediction subject will transition from a first state s to a second state s? after a first time (?t) has elapsed, is expressed by a linear combination of weighted basis functions (model storage unit). A computation device calculates a second state transition probability (attenuation-type state transition probability function D), which indicates the probability that the prediction subject will transition from the first state s to the second state s? after a second time (?t×?) has elapsed, by means of a product-sum computation of a weight matrix ? representing a matrix the elements of which are the respective weights of the weighted basis functions (future state prediction computation unit).
