This package contains the Sockeye project, a sequence-to-sequence framework for Neural Machine Translation based on Apache MXNet (Incubating). It implements state-of-the-art encoder-decoder architectures, such as:

• Deep Recurrent Neural Networks with Attention [Bahdanau, '14]
• Transformer Models with self-attention [Vaswani et al, '17]
• Fully convolutional sequence-to-sequence models [Gehring et al, '17]

In addition, it provides an experimental image-to-description module that can be used for image captioning. Recent developments and changes are tracked in our CHANGELOG.

If you have any questions or discover problems, please file an issue. You can also send questions to sockeye-dev-at-amazon-dot-com.
