  • Publication number: 20230071293
    Abstract: A learning system for performing reinforcement learning of a cooperative action by agents includes the agents; and a reward granting unit configured to grant a reward. The reward granting unit performs a step of, in the presence of a target agent to which the reward is to be granted, calculating an evaluation value relating to a cooperative action of other agents as a first evaluation value; a step of, in the absence of the target agent, calculating an evaluation value relating to a cooperative action of the other agents as a second evaluation value; and a step of calculating a difference between the first and second evaluation values as a penalty of the target agent and calculating the reward to be granted to the target agent based on the penalty. The target agent performs learning of the decision-making model based on the reward granted.

  • Publication number: 20230076427
    Abstract: An image forming apparatus includes a liquid discharge device and processing circuitry. The liquid discharge device includes at least one nozzle group, where N represents an integer, to discharge liquid. The processing circuitry causes the first nozzle group to discharge in a first scan, causes the second nozzle group to discharge in a second scan, and causes the N-th nozzle group to discharge in an N-th scan to form a complete image. The processing circuitry, with respect to an image completion rate indicating a rate of an image formed by each of the first nozzle group to the N-th nozzle group in the complete image, sets the image completion rate of a portion of the first nozzle group adjacent to the second nozzle group in the sub-scanning direction to be not higher than the image completion rate of any one of the second nozzle group to the N-th nozzle group.
