Abstract

For the problem of complex network model and large number of redundant parameters in YOLO series object detection algorithm, this paper proposed an adaptive threshold recurrent pruning algorithm, after the base training and sparsity training, it entered into the adaptive threshold pruning module, which evaluated the importance of channels and convolutional layers by scaling factors for the distribution of scaling factors, and learnt to a pruning threshold autonomously. Then it pruned the network model, and this process could be cyclic and applied in channel pruning and layer pruning. The thresholds in this algorithm were not artificially set, but were obtained by learning for the current network structure and obtaining a better streamlined model by pruning. It validated the algorithm experiments on three datasets based on YOLOv3, and the results show that the algorithm shows strong adaptability to different datasets and different network structures, and the model pruned by adaptive threshold which achieves better results in terms of detection accuracy, compression effect, and inference speed compared with the traditional fixed thresholds.
