A people flow prediction system and method are provided, in which a first conversion model for converting virtual getting in and out data before a certain time point into a number of people who appear after the certain time point and a second conversion model for converting the virtual getting in and out data after a certain time point into the number of people who appear before the certain time point are created based on the number of people who appear and the virtual getting in and out data. A prediction model is learned based on the number of people who appear converted by the second conversion model, and a number of people who appear after a certain time point is predicted from the on-site getting in and out data before the certain time point by using the first conversion model and the prediction model.

People flow prediction method and people flow prediction system

This data conversion system is characterized by including: a storage unit that stores a column including a plurality of data elements; a range specification module that specifies the range of each of the data elements of the column; an information amount evaluation module that calculates the information amount of the data element within the specified range of the column; and a change point detection module that detects a point at which a change in the information amount according to a change in the specified range satisfies a predetermined condition.
