English(EN) Credal Large Language Models for Semantic Commitment under Uncertainty

新的 Credal LLM 改进了不确定性表示并减少了幻觉

研究人员引入了 Credal 大型语言模型 (CLLM),以解决 LLM 生成自信但错误的答案的问题。与使用单一预测分布的标准 LLM 不同,CLLM 采用 LoRA 适配器集成来创建 Credal 集。该集合暴露了一系列合理的分布,从而可以推导出更好地反映不确定性的承诺分数。所提出的方法,Credal Token Commitment (CTC) 和 Semantic Commitment Consistency (SCC),在 Gemma-2-9BLlama-3.1-8BQwen2.5-7B 等模型上进行了评估,显示出在问答准确性和校准方面的改进,同时有效跟踪幻觉率。 AI

影响 引入了一种新颖的 LLM 不确定性量化方法,有望提高 AI 应用的可靠性和可信度。
