GaRAGe: A Benchmark with Grounding Annotations for RAG Evaluation

ACL 2025finding

We present GaRAGe, a large RAG benchmark with human-curated long-form answers and annotations of each grounding passage, allowing a fine-grained evaluation of whether LLMs can identify relevant grounding when generating RAG answers. Our benchmark contains 2366 questions of diverse complexity, dynami…

Prompting open-source and commercial language models for grammatical error correction of English learner text

ACL 2024findings

Thanks to recent advances in generative AI, we are able to prompt large language models (LLMs) to produce texts which are fluent and grammatical. In addition, it has been shown that we can elicit attempts at grammatical error correction (GEC) from LLMs when prompted with ungrammatical input sentence…

SceneDiffuser: Efficient and Controllable Driving Simulation Initialization and Rollout

NeurIPS 2024poster

Simulation with realistic and interactive agents represents a key task for autonomous vehicle (AV) software development in order to test AV performance in prescribed, often long-tail scenarios. In this work, we propose SceneDiffuser, a scene-level diffusion prior for traffic simulation. We present a…

Multi-Class Grammatical Error Detection for Correction: A Tale of Two Systems

EMNLP 2021main

In this paper, we show how a multi-class grammatical error detection (GED) system can be used to improve grammatical error correction (GEC) for English. Specifically, we first develop a new state-of-the-art binary detection system based on pre-trained ELECTRA, and then extend it to multi-class detec…
