Claim One:
1. An information processing apparatus comprising: a reward estimator generating unit using action history data, which includes state data expressing a state of an agent, action data expressing an action taken by the agent in the state, and a reward value expressing a reward obtained by the agent as a result of the action, as learning data to generate, through machine learning, a reward estimator that estimates the reward value from inputted state data and action data; an action selecting unit preferentially selecting, out of actions that can be taken by the agent, an action that has a high reward value estimated using the reward estimator and is not included in the action history data; and an action history adding unit causing the agent to carry out the action according to a selection result of the action selecting unit and adding to the action history data the state data and the action data obtained in a process of the action and a reward value obtained as a result of the action in association with each other, wherein the reward estimator generating unit is operable when a set of the state data, the action data, and the reward value has been added to the action history data, to regenerate the reward estimator.
