Machine learning system, machine learning device and machine learning method

A machine learning device, comprising at least:

• a state acquisition unit configured to acquire at least state information regarding a behavior of a person;
• an evaluation unit configured to obtain a value function by evaluating the state information and environment information regarding an environment around the person when acquiring the state information;
• and
• a machine learning classifier that performs reinforcement learning on the value function and selects the environment information when the value function is the highest in order to prompt the person to engage in a target behavior.
