Cosine Distance

Cosine distance measures how similar two objects are based on their direction rather than their size or magnitude. Imagine two arrows pointing from the same starting point; if they point in the exact same direction, their cosine distance is zero, meaning they are very similar. If they point in completely opposite directions, the distance is larger, indicating they are dissimilar. It’s commonly used in text analysis and machine learning to compare the orientation of data points, helping to identify similarities regardless of their magnitude, focusing on the pattern or shape of the data.
