An information processing apparatus includes: a corresponding data calculation unit configured to determine importance of each sample in accordance with a difference between a plurality of pieces of observation information observed when an input is given to an observation target and data of a second type generated by a simulator that simulates the observation target based on a sample of a parameter with respect to a plurality of samples and data of a first type indicating the input, and a degree of influence of the sample on distribution of parameters, and then calculate data that corresponds to the distribution of the parameters; a new parameter sample generation unit configured to generate a new sample of the parameters in accordance with predetermined processing using the data that corresponds to the distribution of the parameters; and an iteration control unit configured to perform control so as to repeat the above processing.
