摘要

The occurrence of an event is estimated from time series information, which is high-dimensional information such as images. For each of multiple time series image groups, which are given an event occurrence time in advance, and which include time series image groups in the case that the event did not occur and time series image groups in the case that the event did occur, a hazard estimation unit 11 estimates the possibility of occurrence of the event in accordance with a hazard function, and a parameter estimation unit 12 estimates a parameter of the hazard function so as to optimize a likelihood function, which is expressed with the occurrence time of the event given to each of the multiple time series image groups and the possibility of occurrence of the event estimated for each of the multiple time series image groups.
