余弦相似度-1代表语义相反？机器学习面试高频陷阱解析
Related Claims
Unverified余弦相似度只关注两个向量夹角的余弦值，完全忽略向量的模长（幅值）83% similarUnverifiedCosine similarity has a value range of [-1, 1]; in semantic retrieval, attention is typically focused only on the positively correlated range of 0 to 1, with values closer to 1 indicating greater semantic similarity.81% similarUnverifiedCosine similarity is a symmetric metric where the similarity between A and B equals the similarity between B and A, making it unable to express the directional fulfillment relationship in resume-job matching.77% similarUnverified相似度检索通常取Top-K（如Top-3或Top-5）最相似的文本块，相似度计算常用余弦相似度或内积66% similarUnverified传统向量检索只能基于语义相似度找到最像的文档片段，无法执行A作用于B、B关联C、C导致D这类链式多跳推理，而知识图谱可通过图遍历算法或图查询语言实现多跳推理64% similar
