En caso de que la cantidad sobre archivos era extremadamente enorme seri­a probable que a lo largo de unos momentos la app nunca responda. Nunca te preocupes, este comportamiento seri­a normal asi­ como durara separado unos segundos o hasta varios min.Continue reading→

Per this case, the activation function does not depend per scores of other classes in \(C\) more than \(C_1 = C_i\). So the gradient respect preciso the each score \(s_i\) mediante \(s\) will only depend on the loss given by its binary problem.

Focal Loss

, from Facebook, sopra this paper. They claim sicuro improve one-tirocinio object detectors using Focal Loss esatto train per detector they name RetinaNet. Focal loss is verso Ciclocross-Entropy Loss that weighs the contribution of each sample to the loss based durante the classification error. The pensiero is that, if a sample is already classified correctly by the CNN, its contribution to the loss decreases.Continue reading→
