template<typename VecType > static double Evaluate (const VecType &a, const VecType &b)

Computes the cosine distance between two points.

The cosine distance (or cosine similarity).

It is defined by

\[ d(a, b) = ac{a^T b}{|| a || || b ||} \].PP and this class assumes the standard L2 inner product.
