Tfjs: Will you support the CTC loss function?

[yohacai]

Is the CTC loss function already supported by tfjs-converte ?

[dsmilkov]

Hi, are you referring to this one: https://www.tensorflow.org/api_docs/python/tf/nn/ctc_loss ? We first need to add it to core. Happy to take contributions, but since we are prioritizing by use-cases, can you share your use-case and model that needs this loss?

Thanks!

Hi, I want to train speech recognition feature with tensorflow.js. and CTC loss function is key for that.
I hope there are some more people interested in CTC loss...

I need to train Speech Recognition and CTC work as loss function.

I hope to see this implemented in Tensorflow.js

Hi everyone, this is a great issue for an external contribution. I'm happy to provide guidance.

@dsmilkov i would like to add support for ctc in tfjs, but i am clueless and do not know where to start.

I wonder if c++ non parallel implementation should be compilable to wasm and be usable from tfjs, rather than writing a js implementation. Nonetheless, i dont mind writing an implementation in js but not sure how to go on about that.

Thanks

And I need ctc loss for OCR. I doubt I can help with that as I don't really understand the https://www.tensorflow.org/api_docs/python/tf/nn/ctc_loss's source code nor can I implement it by the original paper, unfortunately.

Are there any progress on this?
