Abstract

The embodiment of the invention provides a training and testing method, device and equipment for a quantitative neural network model. The training method comprises the following steps: acquiring training data, wherein the training data comprises an image sample and a labe, and the label comprises an identity label of the image sample; inputting the training data into a quantitative neural networkmodel for quantitative processing to obtain quantitative features of the image sample; and training the quantitative neural network model according to the quantitative features to obtain a trained quantitative neural network model. By implementing the embodiment of the invention, the trained quantitative neural network model adopts low-bit quantization processing, the operand is reduced, the operation rate is improved, the method can be more conveniently applied to terminal equipment, the quantitative neural network model is used for face recognition, the quantization error can be minimized, and the recognition precision of the quantitative neural network model is improved.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a training and testing method, device and equipment for a quantized neural network model. Background technique [0002] Face recognition technology has a wide range of applications in practice. With the help of deep learning and convolutional neural network technology, the accuracy of face recognition has made great progress in recent years. However, as the predictions of the neural network model become more accurate and the layers of the neural network become deeper and deeper, complex neural networks cannot be deployed on mobile terminals, let alone real-time reasoning. [0003] Therefore, there is an urgent need for a training method for a quantized neural network model to solve the above technical problems. Contents of the invention [0004] The embodiment of the present application provides a training and testing method, device, equipment and storage medium of a ...
