Abstract: This image change detection device includes a subspace updating unit that, when a determination unit determines that there has been no change, updates a first subspace by rotating the first subspace so that the first subspace approaches a second subspace. When the determination unit determines that there has been no change, a degree-of-change calculating unit calculates the degree of change between the first subspace updated by the subspace updating unit and a second subspace whose bases are left singular vectors of an image in a change detection period next to a change detection period.

Abstract: A signal identifier according to the present disclosed technology includes an inference model that generates a latent variable in which a distribution for each class in a latent space is defined according to a class of classification, and a second latent variable in which a distribution for each large classification in the latent space is defined according to a large classification of a broader concept of the class.

Abstract: This route prediction device includes: an information acquisition circuitry to acquire a position and a speed of an own vehicle, positions and speeds of surrounding vehicles traveling around the own vehicle, and map information around the own vehicle; a cut-in determinator to determine whether or not the surrounding vehicle will cut in onto a traveling lane of the own vehicle, on the basis of an inducing factor of inducing cut-in of another vehicle; an assumptive vehicle setting circuitry to determine a traveling position, on a road, of an assumptive vehicle assumed to influence traveling of a cut-in vehicle determined to cut in, among the surrounding vehicles, using road information obtained from the map information; and a route prediction circuitry to predict a traveling route of one of the surrounding vehicles, on the basis of the traveling position of the assumptive vehicle, and so forth.
