Abstract: This paper summaries the origin and research progress of neural network pruning technologies, divides them into two categories of unstructured pruning with sparse weight parameters and coarse-grained structured pruning, and introduces the representative methods of the two categories in recent years. Because pruning reduces model parameters and compresses the model size, depth models can be applied to embedded devices, showing the importance of pruning in the field of deep learning model compression. In view of the existing pruning technologies, this paper expounds the problems existing in practical applications and measurement standards, and prospects the research and development tendency in the future.

Key words: deep convolutional neural network, deep learning, model compression, pruning
