Computes Proximity in Large Sparse Matrices

v0.5.2 · Apr 25, 2025 · GPL-3
CRAN GitHub Mirror

Description

Computes proximity between rows or columns of large matrices efficiently in C++. Functions are optimised for large sparse matrices using the Armadillo and Intel TBB libraries. Among various built-in similarity/distance measures, computation of correlation, cosine similarity, Dice coefficient and Euclidean distance is particularly fast.
