The Classic Cross-Correlation and the Real-Valued Jaccard and Coincidence Indices

Abstract : In this work we describe and compare the classic inner product and Pearson correlation coefficient as well as the recently introduced real-valued Jaccard and coincidence indices. Special attention is given to diverse schemes for taking into account the signs of the operands, as well as on the study of the geometry of the scalar field surface related to the generalized multiset binary operations underling the considered similarity indices. The possibility to split the classic inner product, cross-correlation, and Pearson correlation coefficient is also described.
