Generally, the Euclidean distance between two example vectors (x and y) is defined as: (77)Dx,y=x-y⊤x-y=∥x-y∥2. An intuitive method is to minimize the distance between faces from the same person and maximize it when the faces come from different people. Early methods [99,101]...

Chebyshev distance is a metric defined on a vector space where the distance between two vectors is the greatest of their differences along any coordinate dimension [29]. The mathematical definition of Chebyshev metric is derived from Minkowski distance [32]. For variable x and x′, Minkowski dist...
I don't understand how the dist() function works that computes the euclidean distance between two vectors. I created the simplest one dimensional vectors and I would like an explanation of the result I am getting. Here is the vector as an CSV file called test.csv: ...
2. 距离可以用来表征相似度,比如1和2就比1和4更相似; 3. 欧氏距离就是我们最常见的几何距离,比较直观; 那么什么时候求相关性,什么时候求相似度呢? 基因表达当然要求相关性了,共表达都是在求相关性,就是基因A和B会在不同样本间同增同减,所以相关性是对变量而言的,暂时还没听说对样品求相关性,没有意义,总...
