Code generation method and related device based on grammar discriminator

Existing code generation models rely on learning the semantic association between natural language descriptions and codes to generate code, and lack explicit constraints on the grammatical structure of the code, which may lead to grammatical errors in the generated code. In order to solve the problem of grammatical errors in the code, some methods perform grammatical corrections on the generated code through post-processing, but post-processing is an independent step, separated from the code generation model itself, and cannot directly affect the generation ability of the model during the code generation process. In addition, most post-processing methods are based on static rules, which may be difficult to adapt to complex code structures or flexible grammars. In this regard, the present application discloses a code generation method and related equipment based on a grammar discriminator, which includes: inputting the generation description information corresponding to the code to be generated into the code generation model, and obtaining the target code output by the code generation model.
