WebDec 16, 2024 · A Connectionist Temporal Classification Loss, or CTC Loss, was designed for such problems. Essentially, CTC loss is computed using the ideas of HMM … WebMay 14, 2024 · For batch_size=2 the LSTM did not seem to learn properly (loss fluctuates around the same value and does not decrease). Upd. 4: To see if the problem is not just a bug in the code: I have made an artificial example (2 classes that are not difficult to classify: cos vs arccos). Loss and accuracy during the training for these examples:
