Auto-Train-Once: Controller Network Guided Automatic Network Pruning from Scratch

This repository is the Pytorch implementation of Auto-Train-Once (ATO). ATO is an automatic network pruning algorithm designed to dynamically reduce the computational and storage costs of DNN with a controller network. It can train and prune deep learning models automatically and completely end-to-end. After model training, we can directly obtain the compressed model without additional fine-tuning steps. Importantly, our method does not rely on the specific projectors compared with OTO and OTOv2. Additionally, we provide a comprehensive complexity analysis to ensure the convergence of our algorithm, covering both the general non-adaptive optimizer (e.g. SGD) and the adaptive optimizer (e.g. ADAM).
