OCR is still a very hard problem. We don't have universal powerful solutions. We use the CTC loss function An Intuitive Explanation of Connectionist Temporal Classification | Towards Data Science Sequence Modeling With CTC | Distill which is very…

I am trying to implement CTC loss in TensorFlow, but their documentation is pretty limited. So I am not sure how to approach the problem. I found a good example in Theano. Are any other resources that explain the CTC loss? I am also trying to…

Problem Context: I'm building a Morse code audio decoder using CNN-BiLSTM with CTC loss. My current 4-layer model achieves Levenshtein distance ≈0.6, but attempts to improve performance by adding a 5th CNN layer caused training collapse (loss stuck…

I am trying to train an LSTM using CTC loss, but the loss does not decrease when I train it. I have created a minimal example of my issue by creating training data where the network simply has to copy the current input element at each time step.…
