Abstract：To remove redundant structures from deep neural networks and find a network structure with a good balance between capability and complexity, a label-free global compression learning method(LFGCL) is proposed. A global pruning strategy is learned based on the network architecture representation to effectively avoid the appearance of the suboptimal compression rate owing to network pruning in a layer-by-layer manner. LFGCL is independent from data labels during pruning, and the network architecture is optimized by outputting similar features with the baseline network. The deep deterministic policy gradient algorithm is applied to explore the optimal network structure by inferring the compression ratio of all layers through reinforcement learning. Experiments on multiple datasets show that LFGCL generates better performance.
