Less is More: Proxy Datasets in NAS approaches

1 code implementation14 Mar 2022 Brian Moser, Federico Raue, Jörn Hees, Andreas Dengel

One of our surprising findings is that in most cases we can reduce the amount of training data to 25\%, consequently reducing search time to 25\%, while at the same time maintaining the same accuracy as if training on the full dataset.
