Memory-assisted prompt editing to improve GPT-3 after deployment
April 20, 2022Large LMs such as GPT-3 are powerful, but can commit mistakes that are obvious to humans. Memory-assisted prompt editing allows users to give…
DREAM: Improving Situational QA by First Elaborating the Situation
March 1, 2022When people answer questions about a specific situation, e.g., "I cheated on my mid-term exam last week. Was that wrong?", cognitive science suggests…
Explaining Answers with Entailment Trees
November 1, 2021EntailmentBank is a unique dataset of multi-step entailment trees. Each tree shows how known facts combine to entail the answer to a question. From…

Research Areas
Teachable Reasoning Systems
By interacting with and giving feedback on a system’s reasoning, a user can teach the system so it continually improves over time – without model retraining.
Neuro-Symbolic Reasoning and Explanation
Solving problems by generating consistent, faithful chains of reasoning using neural components.
Modular Models
By learning to chain together existing models, complex problems can be solved, beyond the capabilities of the individual components.
Universal Mathematical Reasoners
Creating models with built-in mathematical reasoning skills, that can be rapidly fine-tuned for a wide variety of mathematical tasks.
Macaw is a high-performance question-answering (QA) model capable of outperforming other popular current language models, all while being an order of magnitude smaller. This demo allows you to explore Macaw's answers and compare them to those of the popular GPT-3 language model on a benchmark set of questions.

Self-Refine: Iterative Refinement with Self-Feedback
Aman Madaan, Niket Tandon, Prakhar Gupta, Skyler Hallinan, Luyu Gao, Sarah Wiegreffe, Uri Alon, Nouha Dziri, Shrimai Prabhumoye, Yiming Yang, Shashank Gupta, Bodhisattwa Prasad Majumder, K. Hermann, S. Welleck, A. Yazdanbakhsh, Peter ClarkNeurips • 2023 Like humans, large language models (LLMs) do not always generate the best output on their first try. Motivated by how humans refine their written text, we introduce Self-Refine, an approach for improving initial outputs from LLMs through iterative feedback…A Logic for Expressing Log-Precision Transformers
William Merrill, Ashish SabharwalNeurIPS • 2023 One way to interpret the reasoning power of transformer-based language models is to describe the types of logical rules they can resolve over some input text. Recently, Chiang et al. (2023) showed that finite-precision transformers can be equivalently…How Far Can Camels Go? Exploring the State of Instruction Tuning on Open Resources
Yizhong Wang, Hamish Ivison, Pradeep Dasigi, Jack Hessel, Tushar Khot, Khyathi Raghavi Chandu, David Wadden, Kelsey MacMillan, Noah A. Smith, Iz Beltagy, Hanna HajishirziNeurIPS • 2023 In this work we explore recent advances in instruction-tuning language models on a range of open instruction-following datasets. Despite recent claims that open models can be on par with state-of-the-art proprietary models, these claims are often accompanied…Editing Common Sense in Transformers
Anshita Gupta*, Debanjan Mondal*, Akshay Krishna Sheshadri*, Wenlong Zhao, Xiang Lorraine Li*, Sarah Wiegreffe*, Niket Tandon*EMNLP • 2023 Editing model parameters directly in Transformers makes updating open-source transformer-based models possible without re-training. However, these editing methods have only been evaluated on statements about encyclopedic knowledge with a single correct answer…Increasing Probability Mass on Answer Choices Does Not Always Improve Accuracy
Sarah Wiegreffe, Matthew Finlayson, Oyvind Tafjord, Peter Clark, Ashish SabharwalEMNLP • 2023 When pretrained language models (LMs) are applied to discriminative tasks such as multiple-choice questions, they place probability mass on vocabulary tokens that aren't among the given answer choices. Spreading probability mass across multiple surface forms…
