The Design and Implementation of fastai for PyTorch

The recently-released fastai library introduces a number of new concepts (such as the Data Block API, and consolidated optimized data augmentation), and takes some existing concepts further than they've been taken before (such as a callbacks system on which every piece of training functionality is built, including mixed precision training, mixup augmentation, and more). In this talk we will outline some of the new approaches in fastai, explain how they impact developers, researchers, and users, and show some of the more interesting implementation details behind them.
