We specify the metric type as "cosine" and dimension as 768 because the retriever we use to generate context embeddings outputs 768-dimension vectors. Pinecone will use cosine similarity to compute the similarity between the query and table embeddings.

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 … See more The cosine of two non-zero vectors can be derived by using the Euclidean dot product formula: Given two n-dimensional vectors of attributes, A and B, … See more The ordinary triangle inequality for angles (i.e., arc lengths on a unit hypersphere) gives us that See more • Sørensen–Dice coefficient • Hamming distance • Correlation • Jaccard index • SimRank See more The most noteworthy property of cosine similarity is that it reflects a relative, rather than absolute, comparison of the individual vector dimensions. For any constant $${\displaystyle a}$$ and vector $${\displaystyle V}$$, the vectors $${\displaystyle V}$$ See more A soft cosine or ("soft" similarity) between two vectors considers similarities between pairs of features.

Cosine Similarity Intuition With Implementation in Python
WebJun 17, 2024 · Cosine similarity is used to determine the similarity between documents or vectors. Mathematically, it measures the cosine of the angle between two vectors projected in a multi-dimensional space.There are other similarity measuring techniques like Euclidean distance or Manhattan distance available but we will be focusing here on the Cosine … WebMay 30, 2016 · cosine_similarity is defined as value between -1 to 1, cosine_distance is defined as: 1 - cosine_similarity --> hence cosine_distance range is 0 to 2. – Yaron.
