Learning apparatus, image identification apparatus, learning method, image identification method, and storage medium

A learning apparatus comprising:

• one or more processors;
• and
• a memory coupled to the one or more processors and storing instructions which, when executed by the one or more processors, cause the learning apparatus to perform operations including:
• acquiring a plurality of learning data sets, wherein each learning data set includes one image of a plurality of images, wherein the one image is imaged by one imaging device of a plurality of imaging devices, and acquiring sensor information representing an imaging environment of the one imaging device, wherein the sensor information is sensed by at least one of a plurality of predetermined types of sensors corresponding to the one imaging device when the one image is imaged,
• creating, from the plurality of learning data sets, a plurality of subsets, wherein each subset of the plurality of subsets corresponds to sensor information representing imaging environments sensed by a different one type of, or a different combination of, a plurality of types of sensors, and
• learning each of a plurality of first classifiers based on respective one subset of the plurality of subsets corresponding to that one of the plurality of first classifiers.
