While domain transfer methods (e.g., domain adaptation, domain generalization) have been proposed to learn transferable representations across domains, they are typically applied to ResNet backbones pre-trained on ImageNet. Thus, existing works pay little attention to the effects of pre-training on domain transfer tasks. In this paper, we provide a broad study and in-depth analysis of pre-training for domain adaptation and generalization, namely: network architectures, size, pre-training loss, and datasets. This repository contains PyTorch implementation of the single domain generalization experiments, which can be used as a baselin for domain transfer tasks including domain generalization and adpatation. This implementation is based on Transfer Learning Library.
