In Milvus, the Tanimoto coefficient is only applicable for a binary variable, and for binary variables, the Tanimoto coefficient ranges from 0 to +1 (where +1 is the highest similarity). For binary variables, the formula of Tanimoto distance is: Tanimoto distance. The value ranges from 0 to +infinity. sailing background imagesIn 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.
