Abstract: A non-transitory computer-readable storage medium storing a prediction program that causes at least one computer to execute a process, the process includes simulating a flow of people based on a plurality of behavior intentions of people; evaluating the simulated flow based on observation data of the flow of people; and predicting the flow of people based on an evaluation result of the simulated flow of people.

Abstract: Information for determining whether to evacuate or not is provided to a user by a computerized process. The process includes: acquiring a number of evacuees for each of a plurality of targets corresponding to a predetermined user; selecting a target of the plurality of targets based on the acquired numbers of evacuees for the plurality of targets and importance levels respectively set for the plurality of targets; and associating information on the selected target with information on the acquired number of evacuees for the selected target and outputting the information on the selected target and the information on the acquired number of evacuees for the selected target to the predetermined user.

Abstract: A machine learning method implemented by a computer includes: acquiring simulation conditions including a shape of an object and an inflow velocity of fluid; identifying, based on the shape of the object and the inflow velocity that have been acquired, a position of a boundary layer with respect to the object, a diffusion range of the fluid, and a flow velocity diffusion range of a wake flow of the fluid; creating training data associating the position of the boundary layer, the diffusion range of the fluid, and the flow velocity diffusion range of the wake flow of the fluid that have been identified with a flow velocity field under the simulation conditions; and generating a model that estimates the flow velocity field from the simulation conditions by using the training data.
