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: https://github.com/mohammadpz/CTC-Connectionist-Temporal-Classification/blob/master/ctc_cost.py.
Are any other resources that explain the CTC loss?
Also, I am trying to understand how its forward-backward algorithm works. And what is beam decoder in the case for CTC loss?
