UnverifiedConstrained Decoding computes the set of valid tokens at each token step of autoregressive generation based on a finite state machine or context-free grammar and renormalizes the probabilities, mathematically guaranteeing that the output conforms to the target schema.75% similarUnverifiedThe open-source libraries Outlines and Guidance adopt constrained decoding technology, directly intervening in token sampling during inference.70% similarUnverified从表征到有限词汇的映射过程本质上是一种有损编码（Lossy Encoding）68% similarUnverifiedConstrained Decoding guarantees at the sampling level that outputs will conform to a specified JSON Schema or regular expression; typical open-source implementations include Outlines, Guidance, and LM Format Enforcer.68% similarUnverified在高精度要求的专业领域，可将确定性语法规则编码为硬规则用于校验大模型输出，配合人工校验（Human-in-the-Loop）建立内容权威性67% similar
