From Pixels to UI Actions: Learning to Follow Instructions via Graphical User Interfaces

NeurIPS 2023spotlight

Much of the previous work towards digital agents for graphical user interfaces (GUIs) has relied on text-based representations (derived from HTML or other structured data sources), which are not always readily available. These input representations have been often coupled with custom, task-specific…

Open-domain Visual Entity Recognition: Towards Recognizing Millions of Wikipedia Entities

ICCV 2023oral

Large-scale multi-modal pre-training models such as CLIP and PaLI exhibit strong generalization on various visual domains and tasks. However, existing image classification benchmarks often evaluate recognition on a specific domain (e.g., outdoor images) or a specific task (e.g., classifying plant sp…

Pix2Struct: Screenshot Parsing as Pretraining for Visual Language Understanding

ICML 2023oral

Visually-situated language is ubiquitous---sources range from textbooks with diagrams to web pages with images and tables, to mobile apps with buttons and forms. Perhaps due to this diversity, previous work has typically relied on domain-specific recipes with limited sharing of the underlying data,…

Nearest Neighbor Machine Translation

ICLR 2021poster

We introduce $k$-nearest-neighbor machine translation ($k$NN-MT), which predicts tokens with a nearest-neighbor classifier over a large datastore of cached examples, using representations from a neural translation model for similarity search. This approach requires no additional training and scales…

Generalization through Memorization: Nearest Neighbor Language Models

ICLR 2020poster

We introduce $k$NN-LMs, which extend a pre-trained neural language model (LM) by linearly interpolating it with a $k$-nearest neighbors ($k$NN) model. The nearest neighbors are computed according to distance in the pre-trained LM embedding space, and can be drawn from any text collection, including…
