相关性感知过程（Relevance-Aware Process, RAP）
选择默认的检索器（如DPR和Contriever）来检索与问题相关的文档。
指导模型评估检索到的文档与问题的相关性，并生成解释为何这些文档被识别为相关的输出。
如果所有检索到的文档都不相关，模型应依据预训练阶段获得的内部知识提供答案。
证据感知选择过程（Evidence-Aware Selective Process, EAP）
要求模型从检索到的文档中明确选择关键句子作为证据，并输出选择这些句子的原因。
模型需要自动选择文档中的关键句子片段，并解释为何这些片段能够回答问题。
轨迹分析过程（Trajectory Analysis Process, TAP）
将前两个过程中生成的自我推理轨迹整合，形成推理片段链，以增强检索增强生成的整体性能。
要求模型分析这些推理轨迹，并最终输出简洁的分析和简短的答案。
训练数据生成：使用GPT-4生成答案作为基准真值，并创建正负样本对。
数据质量控制：通过自动验证工具和过滤不正确答案的轨迹，确保数据生成的正确性和完整性。
使用标准的语言建模目标进行训练，通过最大化似然函数来训练自我推理生成模型。
提出了分阶段掩码策略的逐步训练方法，以逐步学习生成长推理轨迹。
此外，还包括数据生成和质量控制的过程：
模型训练：
通过在四个公共数据集（两个短形式问答数据集、一个长形式问答数据集和一个事实验证数据集）上的评估，证明了该方法的优越性，能够超越现有的最先进模型，并且在仅使用2,000个训练样本的情况下，就能与GPT-4的性能相媲美。
