In the PyTorch specific implementation of CTC Loss, we can specify a flag zero_infinity, which explicitly checks for such cases, zeroes out the loss and the gradient if such a case occurs. The flag allows ... Webclass torch.nn.CTCLoss(blank=0, reduction='mean', zero_infinity=False) [source] The … To analyze traffic and optimize your experience, we serve cookies on this …
WebIndeed from the doc of CTCLoss (pytorch): ``'mean'``: the output losses will be divided by the target lengths and then the mean over the batch is taken. To obtain the same value: 1- Change the reduction method to sum: ctc_loss = nn.CTCLoss (reduction='sum') 2- Divide the loss computed by the batch_size: WebYou may also want to check out all available functions/classes of the module torch.nn , or …
