首先来说一下欧氏距离(Euclidean Distance): n维空间里两个向量X(x1,x2,…,xn)与Y(y1,y2,…,yn)之间的欧氏距离计算公式是: 用矩阵表示法表示为: 再来说一下余弦相似度(Cosine Similarity): n维空间里两个向量x(x1,x2,…,xn)与y(y1,y2,…,yn)之间的余弦相似度计算公式是: 用向量形式表示为: 相同...

Indeed, r13 = 1, indicating complete similarity, while r12 and r23 are much lower. Since both r = 1 and r = − 1 are considered to indicate absolute similarity and if, as with Euclidean distance, one would like the numerical value of the similarity measures to increase with increasing ...
