Electronic apparatus for training classification network and operating method thereof, and electronic apparatus using classification network

Abstract

An electronic apparatus includes a memory for storing a classification network including a plurality of feature extraction layers. The electronic apparatus also includes a processor for acquiring a class score corresponding to an object, which is output from the classification network, by inputting a training image including the object to the classification network, acquiring a final loss value, based on a plurality of activation maps respectively output from the plurality of feature extraction layers and the class score, and controlling the classification network, based on the final loss value.
