LLM文档提取技术对抗幻觉

大型语言模型(LLM)在文档提取过程中可能会出现幻觉,即捏造或错误归因信息,导致出现虚构的发票总额或不正确的供应商名称等错误。为解决此问题,技术包括将提取的值与其在源文档中的位置进行关联(grounding),使用校准的置信度分数(而非原始模型概率)来反映实际准确性,以及通过显式模式(schemas)约束提取以强制执行数据类型和结构。这些方法旨在使幻觉可检测和可管理,将风险转变为可审查的任务。 AI

影响 提高基于LLM的文档处理的可靠性,减少业务流程中的代价高昂的错误。

    如何减少文档提取中大型语言模型的幻觉

    <p>A hallucination in LLM document extraction is a value the model returns that does not appear in the document: an invented invoice total, a date lifted from the wrong field, a supplier name completed from the model's memory instead of the page. In an extraction pipeline this is…
