Query: Decomposing neural networks as mappings of correlation functions   Understanding the functional principles of information processing in deep
neural networks continues to be a challenge, in particular for networks with
trained and thus non-random weights. To address this issue, we study the
mapping between probability distributions implemented by a deep feed-forward
network. We characterize this mapping as an iterated transformation of
distributions, where the non-linearity in each layer transfers information
between different orders of correlation functions. This allows us to identify
essential statistics in the data, as well as different information
representations that can be used by neural networks. Applied to an XOR task and
to MNIST, we show that correlations up to second order predominantly capture
the information processing in the internal layers, while the input layer also
extracts higher-order correlations from the data. This analysis provides a
quantitative and explainable perspective on classification.
