WebJun 15, 2024 · CTC For loss calculation, we feed both the ground truth text and the matrix to the operation. The ground truth text is encoded as a sparse tensor. The length of the input sequences must be passed to both CTC operations. We now have all the input data to create the loss operation and the decoding operation. Training WebAug 29, 2024 · The Training Loop. The above code snippet builds a wrapper around pytorch’s CTC loss function. Basically, what it does is that it computes the loss and passes it through an additional method called debug, which checks for instances when the loss becomes Nan..
