English(EN) LEGIT: Live Eligibility Gating over Identifier Tries for Constrained Decoding of Heterogeneous Pages

新的LEGIT系统增强了生成推荐器的约束解码

研究人员开发了一种名为LEGIT(实时资格门控通过标识符树)的新方法,以改进生成推荐器的约束解码,特别适用于Uber Eats搜索引擎等应用。该系统解决了确保生成内容(如结果页面上的菜单项)准确反映现实世界资格并避免重复的挑战。LEGIT使用trie来管理目录标识符,并将规则转换为范围查找,从而为每个生成的页面进行独立的目录检查。虽然最初的GPU实现将令牌生成时间增加了五倍,但更优化的CPU-GPU混合方法将此开销降低到约未约束解码成本的1.7倍。 AI
