Style Memory: Making a Classifier Network Generative
Deep networks have shown great performance in classification tasks.However, the parameters learned by the classifier networks usually discard stylistic information of the input, in favour of information strictly relevant to classification.We introduce a network that has the capacity to do both classification and reconstruction by adding a "style memory" to the output layer of the network.We also show how to train such a neural network as a deep multi-layer autoencoder, jointly minimizing both classification and reconstruction losses.The generative capacity of our network demonstrates that the combination of style-memory neurons with the classifier neurons yield good reconstructions of the inputs when the classification is correct.We further investigate the nature of the style memory, and how it relates to composing digits and letters.
Augmenting the top layer of a classifier network with a style memory enables it to be generative.This paper proposes to train a classifier neural network not just to classifiy, but also to reconstruct a representation of its input, in order to factorize the class information from the appearance .The paper proposes training an autoencoder such that the middle layer representation consists of the class label of the input and a hidden vector representation
