Neural network pruning---the task of reducing the size of a network by
removing parameters---has been the subject of a great deal of work in recent
years. We provide a meta-analysis of the literature, including an overview of
approaches to pruning and consistent findings in the literature. After
aggregating results across 81 papers and pruning hundreds of models in
controlled conditions, our clearest finding is that the community suffers from
a lack of standardized benchmarks and metrics. This deficiency is substantial
enough that it is hard to compare pruning techniques to one another or
determine how much progress the field has made over the past three decades. To
address this situation, we identify issues with current practices, suggest
concrete remedies, and introduce ShrinkBench, an open-source framework to
facilitate standardized evaluations of pruning methods. We use ShrinkBench to
compare various pruning techniques and show that its comprehensive evaluation
can prevent common pitfalls when comparing pruning methods.
