UnverifiedCosine similarity only cares about vector direction and not length, with values strictly falling in the range [-1, 1].83% similarUnverifiedCosine similarity has a value range of [-1, 1]; in semantic retrieval, attention is typically focused only on the positively correlated range of 0 to 1, with values closer to 1 indicating greater semantic similarity.66% similarUnverifiedVector similarity is typically measured using cosine similarity or inner product, combined with vector databases such as FAISS or Milvus to achieve millisecond-level approximate nearest neighbor search.54% similarUnverifiedPrefix matching requires that only a contiguous sequence starting from the first token that is completely identical can hit the cache.53% similar
