An information processing apparatus according to the application concerned includes an obtaining unit and a generating unit. The obtaining unit obtains a first-type graph including a plurality of node corresponding to a plurality of search target. The generating unit generates, based on placement of the plurality of nodes in the first-type graph, a second-type graph that includes a virtual node representing a node not associated to a search target by adding the virtual node to the first-type graph.

Information processing apparatus and information processing method

A generation device according to the subject application includes an acquiring unit and a generating unit. The acquiring unit acquires multiple pieces of vector information that correspond to each search target during the proximity search. The generating unit generates multiple pieces of centroid information, in which each piece of vector information is related in accordance with a distance for vector quantization, based on multiple pieces of vector information acquired by the acquiring unit such that a difference in the number of pieces of vector information related to each piece of centroid information falls within a predetermined value.

Generation device, generation method, and non-transitory computer-readable recording medium

A delivery device according to the present invention includes a learning image storage unit, a first recognition unit, a second recognition unit, and a registration unit. The learning image storage unit stores at least one piece of learning image. The first recognition unit recognizes a recognition target image using the learning image stored in the learning image storage unit. The second recognition unit recognizes the recognition target image with finer precision than that of the first recognition unit, when the first recognition unit fails to recognize the recognition target image. When the second recognition unit succeeds in recognizing the recognition target image, the registration unit registers information on the successfully recognized recognition target image in a storage unit.
