13. A method for encoding and decoding a feature map, comprising:
acquiring feature map information corresponding to a feature map, and reconstructing the feature map based on the feature map information;
generating an encoded feature map by converting each feature value corresponding to the reconstructed feature map from a real number into an integer;
acquiring the feature map information, and inversely reconstructing the encoded feature map based on feature map information corresponding to the encoded feature map; and
generating a decoded feature map by converting each feature value corresponding to the inversely reconstructed feature map from an integer into a real number,
wherein reconstructing the feature map comprises:
when the feature map is reconstructed using multiple channels, classifying the multiple channels into one or more feature map channel groups based on feature values;
realigning the classified multiple channels in an order of the feature map channel groups; and
reconstructing the realigned multiple channels into one feature map channel.
