Binary classification pytorch loss

WebAfter pytorch 0.1.12, as you know, there is label smoothing option, only in CrossEntropy loss. It is possible to consider binary classification as 2-class-classification and apply CE loss with label smoothing. But I did not want to convert input shape as (2, batch) and target's dtype. So I implemented label smoothing to BCE loss by myself ... WebNov 4, 2024 · PyTorch has a CrossEntropyLoss () class two but it is not compatible with binary classification unless you format the training target values as (1, 0) and (0, 1) instead of 0 and 1. The demo program uses the simplest possible training optimization technique which is stochastic gradient descent (SGD).

WebStores the binary classification label for each element in inputs (0 for the negative class and 1 for the positive class). alpha (float): Weighting factor in range (0,1) to balance positive vs negative examples or -1 for ignore. Default: ``0.25``. gamma (float): Exponent of the modulating factor (1 - p_t) to balance easy vs hard examples.
