Classification: CPC F  G | IPC F  G

Claim 0:
1. A machine learning apparatus for determining an operation condition of a precooling operation or preheating operation of an air conditioner, the machine learning apparatus comprising:
a controller including a computer, the controller being configured to
execute an absence control while a user is absent, the absence control including at least one of the precooling operation or the preheating operation;
acquire, as state variables, room temperature data at a time of the precooling operation or preheating operation, set temperature data, and outside air temperature data;
learn the operation condition of the precooling operation or preheating operation based on the state variables and a reward, the reward is based on a room temperature at an end time of the precooling operation or preheating operation, a set temperature, and an electric energy required until the end time of the precooling operation or preheating operation;

at the end time of the precooling operation or preheating operation, the controller being further configured to
increase the reward if a difference between the room temperature and the set temperature is smaller than a first predetermined value and decrease the reward if the difference is equal to or larger than the first predetermined value, or
increase the reward if the electric energy is smaller than a second predetermined value and decrease the reward if the electric energy is equal to or larger than a second predetermined value.
