Why do Nearest Neighbor Language Models Work?

1 code implementation7 Jan 2023 Frank F. Xu, Uri Alon, Graham Neubig

Language models (LMs) compute the probability of a text by sequentially computing a representation of an already-seen context and using this representation to predict the next word.

Capturing Structural Locality in Non-parametric Language Models

no code implementations ICLR 2022 Frank F. Xu, Junxian He, Graham Neubig, Vincent J. Hellendoorn

Structural locality is a ubiquitous feature of real-world datasets, wherein data points are organized into local hierarchies.

Learning Structural Edits via Incremental Tree Transformations

1 code implementation ICLR 2021 Ziyu Yao, Frank F. Xu, Pengcheng Yin, Huan Sun, Graham Neubig

To show the unique benefits of modeling tree edits directly, we further propose a novel edit encoder for learning to represent edits, as well as an imitation learning method that allows the editor to be more robust.
