InitGen：智能助手交互发起候选生成框架
原标题：InitGen: Candidate Generation for Interaction Initiation in Intelligent Assistants
AI 摘要
OPPO 小布助手团队提出 InitGen 框架，用于智能助手在用户表达意图前生成候选交互查询。该方法联合生成候选集合并通过加权偏好优化对齐用户反馈，权重来自用户活跃度和下游排序分数，同时采用滚动窗口更新策略。在线 A/B 测试中，点击率从 0.95% 提升至 1.61%（相对提升 69.1%），查询曝光量增加 17.9%，完整候选集生成耗时 180 毫秒，已全面部署于月活超 1.5 亿的 OPPO 小布助手。

InitGen: Candidate Generation for Interaction Initiation in Intelligent Assistants Abstract Interaction initiation refers to presenting multiple candidate queries when a user opens an intelligent assistant before expressing any intent for the current session. In production, candidate generation incorporates dynamic context and produces all candidates within a strict latency budget. Learning from user feedback is also difficult since the generator usually produces more candidates than are finally
