Recognizer training apparatus, recognition device, electronic device, and training method

Abstract

An information processing apparatus includes a communicator and a controller. The communicator obtains an image. The controller trains a first object recognizer. The first object recognizer consists of a plurality of stepwise determiners in a multilayer structure. A top-layer determiner classifies a target in the image into one of categories. A lower-layer determiner classifies the target in a category determined by a stepwise determiner in a higher layer into a lower category. The first object recognizer recognizes the target by classifying the target stepwise from a higher layer to a lower layer. The controller causes the stepwise determiners to classify the target in the image obtained by the communicator from a higher layer to a lower layer. The controller trains the first object recognizer by adding a new lower category to a higher category corresponding to a lower-layer determiner that cannot classify the target into an existing lower category.
