Abstract

The invention discloses a model training method and apparatus, an image processing method and apparatus, an electronic device and a storage medium. The model training method comprises the steps of obtaining an initial network model and a target limiting condition; target-defined conditions, the method is based on a preset alternate updating mode, an initial network structure hyper-parameter of aninitial network model and a conventional parameter. And performing iterative updating on the network structure hyper-parameters and the conventional parameters of the network model until convergence to obtain a target network model, the preset alternate updating mode comprising: performing iterative updating on the network structure hyper-parameters for T times based on a preset evolutionary strategy every time S times of iterative updating of the conventional parameters. Implementation of the method, when the image processing model for realizing specific purposes is trained, automatic iterative updating can be performed on the network structure hyper-parameters in the network model based on the preset evolutionary strategy, so that the cost of the model training process is reduced, the model training efficiency is improved, the cost of the whole image processing process is reduced, and the image processing efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a model training, image processing method, device, electronic equipment and storage medium. Background technique [0002] With the development of science and technology and the continuous progress of human society, image processing has been widely used in various industries, and the use of image processing technology has become particularly important. At present, in some image processing scenarios, the image processing model for specific purposes is usually trained based on the initial network model, and the image to be processed is processed with the help of the image processing model. Among them, the model training process mainly involves the network structure hyperparameters of the model and general parameter updates. [0003] In the prior art, when updating the hyperparameters of the network structure of the network model, it mainly relies on manual implemen...
