Title: Image Functions In Neural Networks: A Perspective On Generalization. Abstract: In this work, we show that training with SGD on ReLU neural networks gives rise to a natural set of functions for each image that are not perfectly correlated until later in training. Furthermore, we show experimentally that the intersection of paths for different images also changes during the course of training. We hypothesize that this lack of correlation and changing intersection may be a factor in explaining generalization, because it encourages the model to use different features at different times, and pass the same image through different functions during training. This may improve generalization in two ways. 1) By encouraging the model to learn the same image in different ways, and learn different commonalities between images, comparable to model ensembling. 2) By improving algorithmic stability, as for a particular feature, the model is not always reliant on the same set of images, so the removal of an image may not adversely affect the loss.
