Description

🚀 Feature Request

Biased Beam Search

Motivation

Due to incremental nature of source input in streaming translation, the vanilla beam search based model produces unstable translations causing flickers in the translation. The biased beam search reduces flickers and allows stable translation so that users can follow the translation output.

Pitch

Stable Translation for Re-Translation based Simultaneous, Spoken Language Translation,

Additional context

Implements of biased beam search (Section 4.2) as described in Re-Translation Strategies For Long Form, Simultaneous, Spoken Language Translation, ICASSP 2020
