no code implementations23 Oct 2023 Alexandra Butoi, Tim Vieira, Ryan Cotterell, David Chiang

From these, we also immediately obtain stringsum and allsum algorithms for TAG, LIG, PAA, and EPDA.

Convergence and Diversity in the Control Hierarchy

no code implementations6 Jun 2023 Alexandra Butoi, Ryan Cotterell, David Chiang

Furthermore, using an even stricter notion of equivalence called d-strong equivalence, we make precise the intuition that a CFG controlling a CFG is a TAG, a PDA controlling a PDA is an embedded PDA, and a PDA controlling a CFG is a LIG.

Algorithms for Weighted Pushdown Automata

1 code implementation13 Oct 2022 Alexandra Butoi, Brian DuSell, Tim Vieira, Ryan Cotterell, David Chiang

Weighted pushdown automata (WPDAs) are at the core of many natural language processing tasks, like syntax-based statistical machine translation and transition-based dependency parsing.
