This repository is the official implementation of "Deeply Shared Filter Bases for Parameter-Efficient Convolutional Neural Networks" that is under submission to NeurIPS 2021.
In this paper, we present a recursive convolution block design and training method, in which a recursively shareable part, or a filter basis, is separated and learned while effectively avoiding the vanishing/exploding gradients problem during training.
We conducted experiments under
- python 3.8
- pytorch 1.8, torchvision 0.9, cuda11
