Grounding Open-Domain Instructions to Automate Web Support Tasks

1 code implementation NAACL 2021 Nancy Xu, Sam Masling, Michael Du, Giovanni Campagna, Larry Heck, James Landay, Monica S Lam

RUSS consists of two models: First, a BERT-LSTM with pointers parses instructions to ThingTalk, a domain-specific language we design for grounding natural language on the web.

Ehrhart-Equivalence, Equidecomposability, and Unimodular Equivalence of Integral Polytopes

no code implementations21 Jan 2021 Fiona Abney-McPeek, Sanket Biswas, Senjuti Dutta, Yongyuan Huang, Deyuan Li, Nancy Xu

In this paper, we establish a relationship between Ehrhart-equivalence and other forms of equivalence: the $\operatorname{GL}_n(\mathbb{Z})$-equidecomposability and unimodular equivalence of two integral $n$-polytopes in $\mathbb{R}^n$.
