What is cosine similarity and how is it used in machine learning?

In data analysis, cosine similarity is a measure of similarity between two non-zero vectors defined in an inner product space. Cosine similarity is the cosine of the angle between the vectors; that is, it is the dot product of the vectors divided by the product of their lengths. It follows that the cosine similarity does not depend on the magnitudes of the vectors, but only on their angle. The cosine similarity always belongs to the interval For example, two proportional vectors have a cosine simil… WebNov 17, 2024 · The cosine similarity is very popular in text analysis. It is used to determine how similar documents are to one another irrespective of their size. The TF-IDF text analysis technique helps converting the documents into vectors where each value in the vector corresponds to the TF-IDF score of a word in the document.

WebJan 25, 2024 · To compare the similarity of two pieces of text, you simply use the dot product on the text embeddings. The result is a “similarity score”, sometimes called “ cosine similarity ,” between –1 and 1, where a higher number means more similarity. WebApr 3, 2024 · Cosine similarity One method of identifying similar documents is to count the number of common words between documents. Unfortunately, this approach doesn't scale since an expansion in document size is likely to lead to a greater number of common words detected even among completely disparate topics.
