1.18.28

[1.18.28]

Changed

• Temporarily fixing the pyyaml version to 3.12 as version 4.1 introduced some backwards incompatible changes.

[1.18.27]

Fixed

• Fix silent failing of NDArray splits during inference by using a version that always returns a list. This was causing incorrect behavior when using lexicon restriction and batch inference with a single source factor.

[1.18.26]

Added

• ROUGE score evaluation. It can be used as the stopping criterion for tasks such as summarization.

[1.18.25]

Changed

• Update requirements to use MKL versions of MXNet for fast CPU operation.

[1.18.24]

Added

• Dockerfiles and convenience scripts for running fast_align to generate lexical tables.
  These tables can be used to create top-K lexicons for faster decoding via vocabulary selection (documentation).

Changed

• Updated default top-K lexicon size from 20 to 200.
