Abstract: This application provides a neural architecture search method, an image processing method and apparatus, and a storage medium. The method includes: determining a search space and a plurality of structuring elements, stacking the plurality of structuring elements to obtain an initial neural architecture at a first stage, and optimizing the initial neural architecture at the first stage to be convergent; and after an initial neural architecture optimized at the first stage is obtained, optimizing the initial neural architecture at a second stage to be convergent, to obtain optimized structuring elements, and building a target neural network based on the optimized structuring elements. Each edge of the initial neural architecture at the first stage and each edge of the initial neural architecture at the second stage correspond to a mixed operator including one type of operations and a mixed operator including a plurality of types of operations respectively.

Abstract: A neural network building method and apparatus are disclosed, and relate to the field of artificial intelligence. The method includes: initializing a search space and a plurality of building blocks, where the search space includes a plurality of operators, and the building block is a network structure obtained by connecting a plurality of nodes by using the operator; during training, in at least one training round, randomly discarding some operators, and updating the plurality of building blocks by using operators that are not discarded; and building a target neural network based on the plurality of updated building blocks. In the method, some operators are randomly discarded. This breaks association between operators, and overcomes a co-adaptation problem during training, to obtain a target neural network with better performance.
