Description

Hello,

Is there a plan to implement fully CNN seq2seq models? like this paper from Facebook https://arxiv.org/pdf/1705.03122.pdf I can see that there is a CNN encoder, but still not a decoder. It would be great to have it as well in OpenNMT-tf.

Thanks

Contributor guide

Research direction
Read the referenced paper (https://arxiv.org/pdf/1705.03122.pdf) to understand the CNN decoder architecture; examine the existing CNN encoder implementation in OpenNMT tf to mirror the design; implement a decoder class following the paper's description and integrate it into the training pipeline.
