Abstract: A control device generates a state sequence including a plurality of states from a state at a movement source to a state at a movement destination of a physical object. The control device determines the occurrence of an error in an operation of a robot based on a result of comparing the state of the generated state sequence with a state of the physical object during the operation of the robot operating according to the state sequence. The control device changes the state sequence so that a recovery operation for recovering from the error is performed in a case where it is determined that the error has occurred.

Abstract: Information processing apparatus includes: an observation unit that observes situations and speeds of agents; a task weight estimation unit that estimates second task weights with reference to a first model based on the observed positions, the observed speeds, and first task weights indicating set execution probabilities of tasks by the agents, the second task weights indicating execution probabilities of the tasks by the agents under the observed statuses; and a task weight update unit that updates the first task weights by inputting the observed positions, the observed speeds, and the second task weights to a second model. When one of a position and a speed has been input together with a weight coefficient, the first model outputs the other of the position and the speed. The second model increases a value of a first weight as a cost calculated using a position, a speed, and a second task weight decreases.
