Mahalanobis distance

[ligesangmeiduo]

Thank you for sharing, but I have a question for you. The paper says to learn a Mahalanobis distance and map it to the Mahalanobis distance through the extracted features. The feature is that the model is completed in the classification stage, so it is obtained again through the Mahalanobis distance. Is the result of another model? Can it be understood as a phased training model?
