Reinforcement learning device, reinforcement learning method, and recording medium

A reinforcement learning method to be executed by a reinforcement learning device, the reinforcement learning device including a processor configured to execute a program and a storage device configured to store the program, the reinforcement learning method comprising:

• generation processing, executed by the processor, of generating a behavior of an environment;
• calculation processing, executed by the processor, of calculating, based on an action on the environment and the behavior generated in the generation processing, a mimicry reward indicating how much the action mimics the behavior;
• collection processing, executed by the processor, of selecting the action on the environment based on a policy and collecting experience data including the action, a state of the environment when the action is performed on the environment, and a reward obtained from the environment as a result of performing the action;
• and
• learning processing, executed by the processor, of learning the policy based on the reward collected in the collection processing and the mimicry reward calculated in the calculation processing.

A non-transitory recording medium storing a reinforcement learning program for causing a processor to execute:

• generation processing of generating a behavior of an environment;
• calculation processing of calculating, based on an action on the environment and the behavior generated in the generation processing, a mimicry reward indicating how much the action mimics the behavior;
• collection processing of selecting the action on the environment based on a policy and collecting experience data including the action, a state of the environment when the action is performed on the environment, and a reward obtained from the environment as a result of performing the action;
• and
• learning processing of learning the policy based on the reward collected in the collection processing and the mimicry reward calculated in the calculation processing.
