Similarity Matrix


A similarity matrix of scores expresses the similarity between two data points. Similarity matrices are strongly related to their counterparts, distance matrices and substitution matrices. Similarity of Matrix Representations is related to "Diagonal Matrix Representation." Similarity matrices are used in sequence alignment. Higher scores are given to more-similar characters, and lower or negative scores for dissimilar characters. Below is a similarity analysis of the timestamps of digital photographs to cluster photos.
