Connectionist Temporal Classification example #32
Description
Activity
Thank you for inquiring. We are working on an implementation. It will be released if/when we are happy with its performance, API, and documentation.
Here's another request for a CTC layer / objective. I'm working on speech modeling, and CTC is pretty much essential to this.
Here here, I'm working on speech modeling too. A CTC implementation will help my effort greatly.
Just an update on timelines: we're getting closer but it won't happen before January sometime at the earliest.
Baidu has just released a fast open source implementation of CTC for CPUs and GPUs.
https://github.com/baidu-research/warp-ctcIt has a very simple C interface and it should hopefully be fairly easy to create Tensorflow bindings (we're happy to help). The release includes Torch bindings.
China is out silicon valleying silicon valley!
We're closer. Still cleaning up code for release.

.Hi Ebrevdo,
A CTC implementation would be really useful to me for some genome analysis tasks that are handled poorly by HMM approaches.
Matthew
Coming very soon (I hope).

.The CTC loss and two decoders (greedy & beam search for CTC) should be in the next push.
(it'll be accessible via tf.contrib.ctc.ctc_loss etc.)

I found these lines in array_grad.py
Is there any implementation of CTC cost function in tensorflow, or any example concern CTC ?
