func CosineDistance ¶

func CosineDistance(a, b []float32) float32

CosineDistance calculates the cosine distance between two vectors. The cosine distance is defined as 1 - (dot product of a and b) / (magnitude of a * magnitude of b). The result is in the range [0, 2], where 0 means the vectors are identical and 2 means they are opposite.
