CNN decoder

[AbdallahNasir]

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

Hi,

We would accept a contribution for this decoder, but it seems to me that this model is now superseded by the Transformer model. Are CNN encoders and decoders still used?

Fully CNN is doing better on some experiments on seq2seq tasks than transformers.
