  • Abstract: We study the interplay between memorization and generalization of overparametrized networks in the extreme case of a single training example. The learning task is to predict an output which is as similar as possible to the input. We examine both fully-connected and convolutional networks that are initialized randomly and then trained to minimize the reconstruction error. The trained networks take one of the two forms: the constant function (``memorization'') and the identity function (``generalization''). We show that different architectures exhibit vastly different inductive bias towards memorization and generalization.
