Abstract: A hazard estimation unit 21 estimates a likelihood of an occurrence of an event according to a hazard function, with respect to each of a plurality of pieces of time-series data that are a series of multiple pieces of data to which an event occurrence time relevant to the data is given in advance and that include time-series data in which the event did not occur and time-series data in which the event occurred. A parameter estimation unit 22 estimates a parameter of the hazard function so as to optimize a likelihood function expressed by including the event occurrence time given with respect to each of the plurality of pieces of time-series data and the likelihood of the occurrence of the event estimated with respect to each of the plurality of pieces of time-series data.

Abstract: An intersection determination is made regarding whether or not a traffic route included in map information intersects a boundary between areas on a basis of the traffic route and an area shape between areas that are adjacent in the map information, the intersection determination being made for each pair of adjacent areas. On a basis of a weight determined for the boundary in a case where the intersection determination is made that no intersection exists, a movement cost graph expressing a movement cost for each area that accounts for the weight is constructed. A corrected shortest distance between areas is calculated on a basis of the movement cost graph. A human mobility between areas is estimated for each timestep, the timestep being the length of a predetermined time interval, according to a predetermined function for estimating the human mobility between areas on a basis of the corrected shortest distance between areas and a population of each of the areas at different predetermined times.

Abstract: A destination of a user is predicted with high accuracy while the user is moving regardless of whether past movement trajectory data of the user does not exist or the past movement trajectory data of the user exists.

Abstract: A solution to an optimization problem can be obtained while reducing the amount of computation. An optimization problem reformulating unit 130 reformulates an optimization problem as a processing target into an optimization problem in which a constraint on a discrete variable and a constraint on a continuous variable are separated. A discrete variable optimizing unit 160 optimizes the discrete variable in the reformulated optimization problem while fixing the continuous variable at a certain point. A continuous variable optimizing unit 180 optimizes the continuous variable in the reformulated optimization problem while fixing the discrete variable to a certain point. A link changing unit 200 changes a link coefficient representing the influence of a term in which the discrete variable and the continuous variable are multiplied by each other in the reformulated optimization problem.

Abstract: A human migration number can be estimated as an integer value with high accuracy without depending on the size of an area. A human migration number between areas at each time is estimated on the basis of the population of each of the areas at the time under a constraint that the population of each of the areas at each time and a human migration number between the areas at the time are in a predetermined relation and that the human migration number between the areas at the time is an integer value in order to maximize a likelihood function expressed using the population of each of areas at each time, the human migration number between the areas at the time, and the migration probability between the areas, the migration probability between the areas is estimated on the basis of the estimated human migration number between the areas at the time in order to maximize the likelihood function, and the estimation processing is repeated until a predetermined condition is satisfied.

Abstract: It is possible to accurately predict data for a prediction target time. The operation unit 10 receives high-dimensional array data representing data at each time and external information data that is a tensor or matrix representing external information at each time. The parameter estimation unit 16 decomposes the high-dimensional array data into a weighted sum of products of a plurality of factor matrices for each rank and decomposes the external information data into a weighted sum of products of a plurality of factor matrices for each rank, under a sparse constraint of weighting parameters for each rank. The prediction unit 22 predicts the data for a prediction target time based on the weighting parameters for each rank and the plurality of factor matrices for each rank, obtained for the high-dimensional array data.

Abstract: The probability of migration and the number of migrating persons with high accuracy and a small amount of calculation can be estimated even when migrations to areas other than adjacent areas are taken into consideration. A parameter estimation unit 120 estimates a first parameter indicating the likelihood of departure from the area to the other area and a second parameter indicating the likelihood of gathering of persons in the area for each of the plurality of areas, a third parameter indicating an influence on the probability of migration of a distance between the areas, and the number of migrating persons from the area to each of the other areas for each of the plurality of areas on the basis of the demographic information. A migration probability calculation unit 170 calculates the probability of migration from the area to each of the other areas for each of the plurality of areas on the basis of the first parameter, the second parameter, and the third parameter.
