This paper proposes the Euclidean (dis)similarity metric which enables incorporation of risk and return along with the primary correlation component. We apply this metric to explain the collective behavior of the MSCI world market and compare the results with other correlation networks. Findings show ...

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...
