...了指标间的相关性干扰; 不受指标量纲的影响; 对原数据进行线性变换之后,马氏距离不变 相似系数 夹角余弦(Cosin)(cosine similarity余弦相似性) i i x y 2 2 cos , 1 1 i xy i i i i d d x y xy xy 相关系数(...
The important influence factors to TCMF are due to the difference of the main contents of TCM, the Cosin method is better for similarity evaluation than Correlation method.
