大语言模型可以陈述置信度,但校准仍是挑战

研究人员正在探索提高大语言模型(LLM)自我报告置信度水平可靠性的方法。一种关键技术涉及提示大语言模型以百分比形式明确陈述其置信度,然后可以解析并用于门控或路由响应。然而,这些陈述百分比的准确性,即所谓的校准,至关重要且常常缺失。通过按置信度对预测进行分箱并测量经验准确性,或计算预期校准误差(ECE)等方法,用于评估这种校准。由于其训练数据和强化学习(奖励听起来果断的响应),大语言模型往往过于自信。 AI

影响 通过实现对不确定答案的更好门控和路由,提高了大语言模型的响应可靠性。

    口头表达的信心:让大型语言模型说明其确信程度,然后检查90%是否真的等于90%

    <p>Ask a model a question and it answers with the same flat certainty whether it knows the capital of Australia or is guessing a coin-flip. Verbalized confidence fixes half of that: you ask it to attach an explicit self-estimate — "Answer: Canberra, Confidence: 90%." That single …
