Convolutional neural network quantization algorithm based on weight interaction ideas

Abstract：Traditional convolutional neural network quantization algorithms widely use symmetric uniform quantization operations to quantize models′ weights, without taking into account the correlation between the quantization of adjacent weights, that is, the quantization noise generated by the quantization operation of the previous weight can be made up after adjusting the quantitative direction of the next weights. Aiming at the above problems, a ternary convolutional neural network quantization algorithm based on the idea of weight interaction is proposed, the model compression ratio is 16 times. On the ImageNet dataset, the model prediction accuracy of ternarized AlexNet and ResNet-18 network only decrease less than 3%. This method achieves a high model compression ratio, has higher accuracy, and can be used to transplant convolutional neural networks to mobile platforms with limited computing resources.
