Understanding Cosine Similarity Cosine similarity is a metric determining the similarity between two non-zero vectors in a multi-dimensional space. Unlike other similarity measures, such as Euclidean distance, cosine similarity calculates the angle between two vectors rather than their magnitude. ...
