Table Retrieval May Not Necessitate Table-specific Model Design

1 code implementation19 May 2022 Zhiruo Wang, Zhengbao Jiang, Eric Nyberg, Graham Neubig

In this work, we focus on the task of table retrieval, and ask: "is table-specific model design necessary for table retrieval, or can a simpler text-based model be effectively used to achieve a similar result?"

Accurate and Fast Retrieval for Complex Non-metric Data via Neighborhood Graphs

no code implementations8 Oct 2019 Leonid Boytsov, Eric Nyberg

We demonstrate that a graph-based search algorithm-relying on the construction of an approximate neighborhood graph-can directly work with challenging non-metric and/or non-symmetric distances without resorting to metric-space mapping and/or distance symmetrization, which, in turn, lead to substantial performance degradation.
