Emergence of Invariance and Disentanglement in Deep Representations

5 Jun 2017 Alessandro Achille Stefano Soatto

Using established principles from Statistics and Information Theory, we show that invariance to nuisance factors in a deep neural network is equivalent to information minimality of the learned representation, and that stacking layers and injecting noise during training naturally bias the network towards learning invariant representations. We then decompose the cross-entropy loss used during training and highlight the presence of an inherent overfitting term... (read more)
