Cosine Distance
Cosine distance measures the angular distance between two non-zero vectors in a multi-dimensional space. Originally developed by Gerard Salton for information retrieval in 1975, it captures dissimilarity by computing one minus the cosine similarity, ranging from 0 (identical direction) to 1 (opposite direction). It is widely used in text analysis, document comparison, and decision-making contexts where direction matters more than magnitude.
