dgs.models.metric.metric.CosineDistanceMetric¶
- class dgs.models.metric.metric.CosineDistanceMetric(*args: Any, **kwargs: Any)[source]¶
Class to compute the cosine distance between two matrices.
Notes
The cosine distance is the complement of the cosine similarity in positive space:
\[ \begin{align}\begin{aligned}\text{cosine similarity} = S_C(A,B) = \frac{\mathbf{A} \cdot \mathbf{B}}{\|\mathbf{A}\| \|\mathbf{B}\|}\\\text{cosine distance} = 1 - S_C(A,B)\end{aligned}\end{align} \]
