Abstract: An information processing apparatus determines a group, which includes at least two nodes, based on similarity between a plurality of first behavior sets using node information which indicates the plurality of first behavior sets corresponding to the plurality of nodes. The information processing apparatus assigns a second behavior set to the group. The information processing apparatus calculates an evaluation value for each behavior included in the second behavior set without calculating evaluation values for behaviors included in the at least two first behavior sets corresponding to the at least two nodes. The information processing apparatus calculates a probability distribution of the behaviors included in the second behavior set based on the evaluation values.

Abstract: An information processing apparatus generates a data set including a plurality of records each of which indicates one out of a plurality of behaviors. The information processing apparatus calculates a first evaluation value for a first behavior that appears in the data set, based on a distribution of appearance frequency of first behaviors in the data set. The information processing apparatus updates at least a part of the records so that the appearance frequency of a first behavior whose first evaluation value exceeds a threshold increases. The information processing apparatus calculates a second evaluation value for a second behavior that appears in the updated data set based on a distribution of the appearance frequency of second behaviors in the updated data set.

Abstract: A disclosed air conditioning control system includes an electronic apparatus including a heat generating component, a fan that supplies cooling air to the electronic apparatus, and a controlling unit that controls the number of rotations of the fan. The controlling unit controls the number of rotations of the fan by predicting a future temperature of the heat generating component, such that the temperature of the heat generating component lies within an allowable range, in a first case where a rate of rise in a consumed electric power of the electronic apparatus is smaller than a first threshold. In a second case where the rate of rise is equal to or larger than the first threshold, the controlling unit switches the control of the number of rotations of the fan to a control in which the number of rotations of the fan becomes larger than that in the first case.

Abstract: A process includes obtaining, according to a predetermined update order of a policy parameter of each agent, a degree of influence on a constraint specific to a first agent and a degree of influence on a system-wide constraint in which a degree of influence by an updated policy parameter of a second agent previous to the first agent in the update order is shared, and in a case where an update width of the policy parameter of the first agent exists in both ranges respectively determined depending on the degree of influence on the constraint specific to the first agent and the degree of influence on the system-wide constraint, updating the policy parameter of the first agent and causing the degree of influence on the system-wide constraints by the updated policy parameter to be shared with a third agent next to the first agent in the update order.
