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.

Like RuleTaker, ProofWriter determines whether statements are True or False based on rules given in natural language - but also generates the proof of its answers.

Complexity-Based Prompting for Multi-Step Reasoning
Yao Fu, Hao-Chun Peng, Ashish Sabharwal, Peter Clark, Tushar KhotICLR • 2023 We study the task of prompting large-scale language models to perform multi-step reasoning. Existing work shows that when prompted with a chain of thoughts (CoT), sequences of short sentences describing intermediate reasoning steps towards a final answer…Decomposed Prompting: A Modular Approach for Solving Complex Tasks
Tushar Khot, Harsh Trivedi, Matthew Finlayson, Yao Fu, Kyle Richardson, Peter Clark, Ashish SabharwalICLR • 2023 Few-shot prompting is a surprisingly powerful way to use Large Language Models (LLMs) to solve various tasks. However, this approach struggles as the task complexity increases or when the individual reasoning steps of the task themselves are hard to learn…Transformers Can Be Expressed In First-Order Logic with Majority
William Merrill, Ashish SabharwalarXiv • 2023 Characterizing the implicit structure of the computation within neural networks is a foundational problem in the area of deep learning interpretability. Can the inner decision process of neural networks be captured symbolically in some familiar logic? We show…Do language models have coherent mental models of everyday things?
Yuling Gu, Bhavana Dalvi Mishra, Peter ClarkarXiv • 2022 When people think of everyday things like an “egg,” they typically have a mental image associated with it. This commonsense knowledge helps us understand how these everyday things work and how to interact with them. For example, when someone tries to make a…DISCO: Distilling Phrasal Counterfactuals with Large Language Models
Zeming Chen, Qiyue Gao, Kyle Richardson, Antoine Bosselut, Ashish SabharwalarXiv • 2022 Recent methods demonstrate that data augmentation using counterfactual knowledge can teach models the causal structure of a task, leading to robust and generalizable models. However, such counterfactual data often has a limited scale and diversity if…

Multihop Questions via Single-hop Question Composition
Multihop reading comprehension dataset with 2-4 hop questions.
MuSiQue is a multihop reading comprehension dataset with 2-4 hop questions, built by composing seed questions from 5 existing single-hop datasets. The dataset is constructed with a bottom-up approach that systematically selects composable pairs of single-hop questions that are connected, i.e., where one reasoning step requires information from the other. This approach allows greater control over the properties of the resulting k-hop questions, allowing us to create a dataset that is substantially less cheatable (e.g. by shortcut-based or singlehop reasoning) and more challenging than prior similar datasets. MuSiQue comes in two variations -- MuSiQue-Answerable, which contains only answerable questions, and MuSiQue-Full, which contains both answerable and unanswerable questions. In the latter, each answerable question from MuSiQue-Answerable is paired with closely similar unanswerable question. In MuSiQue-Answerable, the task is to identify the answer and the supporting paragraphs, given a question and a context of up to 20 paragraphs. In MuSiQue-Full, the task is to first determine whether the question is answerable from the given context, and if it is, identify the answer and the supporting paragraphs.
