Abstract:One-shot Network Pruning at Initialization (OPaI) is an effective method to decrease network pruning costs. Recently, there is a growing belief that data is unnecessary in OPaI, e.g. [12,32]. However, we obtain an opposite conclusion by ablation experiments in two representative OPaI methods, SNIP [22] and GraSP [37]. Specifically, we find that informative data is crucial to enhancing pruning performance. In this paper, we propose two novel methods, Discriminative One-shot Network Pruning (DOP) and Super Stitc… Show more
