CPOT: Channel Pruning via Optimal Transport [article]

Yucong Shen, Li Shen, Hao-Zhi Huang, Xuan Wang, Wei Liu
2020 arXiv   pre-print
To address such a challenging issue, we propose a new technique of Channel Pruning via Optimal Transport, dubbed CPOT.  ...  Specifically, we locate the Wasserstein barycenter for channels of each layer in the deep models, which is the mean of a set of probability distributions under the optimal transport metric.  ...  Channel Pruning via Optimal Transport (CPOT) In this section, we describe the proposed CPOT algorithm. We first introduce the methodology of optimal transport.  ...
