MOVEMENT MEANS ESTIMATION MODEL GENERATION DEVICE, MOVEMENT MEANS ESTIMATION MODEL GENERATION METHOD, AND MOVEMENT MEANS ESTIMATION MODEL GENERATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To enhance the estimation accuracy of movement means estimation by enabling the extraction of a feature amount which acquires sequence changes of a feature of an individual positioning point from a GPS track.SOLUTION: A sequence expression extraction unit 30 extracts sequence expression having information, such as a movement time to each positioning point on the basis of GPS track segments stored in DBs 10, 20, and stores the sequence expression in DBs 40, 50. A sequence feature amount extraction model generation unit 60 generates a sequence feature amount extraction model on the basis of stored data of the DBs 40, 50, and stores the sequence feature amount extraction model in a DB 70. A sequence feature amount extraction unit 80 extracts a sequence feature amount by using the sequence feature amount extraction model of the DB 70, and stores the sequence feature amount in a DB 90. A feature amount connection unit 120 stores a connection feature amount obtained by connecting the conventional basic feature amount stored in a DB 110 and the sequence feature amount stored in the DB 90 in a DB 130. An estimation model generation unit 140 generates an estimation model on the basis of the stored data of the DB 130, and stores the estimation model in a DB 150.SELECTED DRAWING: Figure 1
