Contrastive center loss pytorch

WebThe loss can be formally written as: The function is a similarity metric, and the hyperparameter is called temperature determining how peaked the distribution is. Since many similarity metrics are bounded, the temperature parameter allows us to balance the influence of many dissimilar image patches versus one similar patch.
