Entailer: Answering Questions with Faithful and Truthful Chains of Reasoning
November 16, 2022 | Bhavana DalviEMNLP '22 Talk for paper: https://www.semanticscholar.org/paper/Explaining-Answers-with-Entailment-Trees-Dalvi-Jansen/4a56f72b9c529810ba4ecfe9eac522d87f6db81d Our goal is a question-answering (QA) system that can show how its answers are implied by its own internal beliefs via a systematic chain of reasoning…
Biomedical AI for Precision Health
August 16, 2022 | Hoifung PoonAbstract: The advent of big data promises to revolutionize medicine by making it more personalized and effective, but big data also presents a grand challenge of information overload. For example, tumor sequencing has become routine in cancer treatment, yet interpreting the genomic data requires painstakingly…
Beyond End-to-end: Decomposed Modeling and Representations in NLP
July 22, 2022 | Ido DaganABSTRACT: Deep learning has pushed us to develop models and representations which we understand and control to a much lesser degree than earlier methods. In this talk I suggest revisiting the pursuit of decomposed models and representations, aiming to regain a better understanding and control of our systems while…
"Computers don't have common sense" with Dr. Oren Etzioni
July 13, 2022 | Oren EtzioniAllen Institute for AI or AI2 is the brainchild of the late Paul Allen, philanthropist, and Microsoft co-founder. Dr. Oren has also been a part of the organisation from its inception. Being a renowned expert in the field of AI and a serial entrepreneur, he has helped pioneer meta-search, online comparison…
Applied AI in High-Expertise Settings, or Curation as Programming
June 29, 2022 | Bill HoweThe success of large AI models in challenging (yet conceptually simple) perception and comprehension tasks (e.g., generating images from a text description) is motivating new applications of these methods in areas previously considered to require human expertise. For example, deep learning has shown promise in…
Machines Making Moral Decisions
June 22, 2022 | Kurt GrayAbstract: Humans are increasingly working with AI-powered algorithms, sharing the road with autonomous vehicles, sharing hospital wards with autonomous surgery robots, and making joint decisions with autonomous algorithms. As we adapt to the increasing presence of AIs playing significant roles in our…
Time Waits for No One! Analysis and Challenges of Temporal Misalignment
June 14, 2022 | Kelvin LuuWhen an NLP model is trained on text data from one time period and tested or deployed on data from another, the resulting temporal misalignment can degrade end-task performance. In this work, we establish a suite of eight diverse tasks across different domains (social media, science papers, news, and reviews) and…
Prompt Waywardness: The Curious Case of Discretized Interpretation of Continuous Prompts
June 10, 2022 | Daniel KhashabiFine-tuning continuous prompts for target tasks has recently emerged as a compact alternative to full model fine-tuning. Motivated by these promising results, we investigate the feasibility of extracting a discrete (textual) interpretation of continuous prompts that is faithful to the problem they solve. In…
DREAM: Improving Situational QA by First Elaborating the Situation
June 7, 2022 | Yuling GuWhen people answer questions about a specific situation, e.g., "I cheated on my mid-term exam last week. Was that wrong?", cognitive science suggests that they form a mental picture of that situation before answering. While we do not know how language models (LMs) answer such questions, we conjecture that they…
Text Modular Networks: Learning to Decompose Tasks in the Language of Existing Models
June 6, 2022 | Tushar KhotNAACL '21 Presentation of our paper: https://api.semanticscholar.org/CorpusID:221448158 We propose a general framework called Text Modular Networks(TMNs) for building interpretable systems that learn to solve complex tasks by decomposing them into simpler ones solvable by existing models. To ensure solvability…
