Cosine similarity is a measure of similarity between two vectors of an inner product space that measures the cosine of the angle between them. The cosine of 0° is 1, and it is less than 1 for any other angle. It is thus a judgment of orientation and not magnitude: two vectors with the same orientation have a cosine similarity of 1, two vectors at 90° have a similarity of 0, and two vectors diametrically opposed have a similarity of -1, independent of their magnitude. Cosine similarity is particularly used in positive space, where the outcome is neatly bounded in [0,1].
Note that these bounds apply for any number of dimensions, and cosine similarity is most commonly used in high-dimensional positive spaces. For example, in information retrieval and text mining, each term is notionally assigned a different dimension and a document is characterised by a vector where the value of each dimension corresponds to the number of times that term appears in the document. Cosine similarity then gives a useful measure of how similar two documents are likely to be in terms of their subject matter.
cosine similarity. # The same README doc on GitHub gives other choices but for most common uses it makes little difference # hence cosine similarity is used as our default ... # the operator is the cosine similarity search.
As part of setting up an index, you’ve already defined the distance metric used to select similar documents ... For most RAG applications you probably want to choose a cosine metric, as this finds documents that are similar to your query term ... .
Cosine similarity uses the cosine of the angle between two vectors; this is easiest to visualize in two or three dimensions, but no matter how high the dimensionality, the cosine ranges from -1 ...
