aspcol.distance.cos_similary

aspcol.distance.cos_similary(vec1, vec2)

Computes <vec1, vec2> / (||vec1|| ||vec2||) which is cosine of the angle between the two vectors.

1 is paralell vectors, 0 is orthogonal, and -1 is opposite directions

Parameters:

• vec1 (np.ndarray of any shape) – First vector. If the arrays have more than 1 axis, it will be flattened.

• vec2 (np.ndarray of same shape as vec1) – Second vector. If the arrays have more than 1 axis, it will be flattened.

Returns:

cos_sim – The cosine similarity between the two vectors

Return type:

float
