Calculate distance between two matricesRichard D. Pearson
SUMMARY Biologists frequently summarize multivariate data from n populations by computing some measure of distance between populations. The problem then arises of comparing two such pairwise distance matrices based on different characters. A permutation test for correlation between distance matrices is propos...
As a first intuition, I've used Matlab corrcoef/corr2 function to compute a correlation coefficient between the two matrices, but it has been pointed out that I should use Spearman's rho instead. As far as I can tell, the function corr calculating Spearman's rho returns a matrix of ...
Sometimes the precision of the two orders can be substantially different (see Supplementary Fig. 2 for a target-by-target comparison of the precision on HeteroTest1 and HeteroTest2). However, a two-sided pairwise t-test shows that there is no significant difference between the two on average....

For classification, we present an AMD metric to calculate the distance between two feature matrices. The results of our experiments show that, BDPCA with AMD metric is very effective in image recognition. 展开 关键词:palmprint recognition PCA 2DPCA image recognition face recognition ...

Two methods of defining the distance between two fuzzy subsets u and v of Rp have been proposed [3], one of which was later modified [9]. In one of the methods in Ref. [3], a distance which is a fuzzy subset of R+ was defined. For a non-negative real number r∈R+, the dist...
