Robot learning and perception for contact-rich manipulation
March 2, 2023 | Samarth BrahmbhattAbstract: Object rearrangement will become an important skill for collaborative robots as they increasingly operate in unstructured environments. Rearrangement involves grasping, goal-conditioned navigation, and placement. In this talk, I will present our latest work, which focuses on placement. We learn a…
Empowering Human-like Decision Making in AI Models through Explanations
February 22, 2023 | Ramasamy Selvaraju RamprasaathAbstract: Deep neural networks have achieved remarkable results in several Computer Vision tasks, but their increasing complexity poses challenges in terms of interpretability. In this talk, I will present my research on explainability in deep learning models, ranging from convolutional neural networks (CNNs) to…
Environment-oriented modeling for grounded NLP and collective intelligence systems
February 21, 2023 | Ronen TamariAbstract: “Ask not what's inside your head, but what's your head inside of” — W.M. Mace, 1977 In contrast to classical cognitive science which studied brains in isolation, ecological cognitive science accounts focus on the role of the body and external environment in shaping cognition. In this talk I will…
Understanding and Improving Compositional Generalization
February 10, 2023 | Ben BoginPre-trained language models perform well on a large variety of question-answering tasks, but they still often fail in the compositional generalization setup, where models are tested on unseen compositions of reasoning skills. In this talk, I will go over three research directions that address this challenge. In…
No Language Left Behind Unlocking Text Data for Under Resourced
February 9, 2023 | Shruti RijhwaniNLP systems are limited by the availability of text data, and because machine-readable text exists only in a few hundred languages, most of the world’s languages are under-represented in modern language technologies. Text data exists in many more languages! However, it is locked away in printed books and…
Artificial Intelligence and Ethics: Towards a Robust Normative Framework
February 8, 2023 | S. Matthew LiaoAbstract: As AI technologies continue to advance, questions about the ethics of AI become more pressing than ever. In this talk, I aim to outline some of the key issues in the study of AI ethics, identify some of the core claims that have been made, and propose an ethical framework that can help us guide these…
What Do NLP Researchers Believe? Results of the NLP Community Metasurvey
January 12, 2023 | Julian Michael/Research Scientist, New York UniversityAbstract: I will present the results of the NLP Community Metasurvey (nlpsurvey.net). This was a questionnaire that we ran from May to June 2022 which elicited the opinions of NLP researchers on controversial issues, including industry influence in the field, concerns about AGI, and ethics. Our results put…
Global storm-resolving climate simulation in Python
December 14, 2022 | Oliver FuhrerThis video shows an animation of a climate simulation done with a Python implementation of NOAA's climate model FV3GFS on the Piz Daint supercomputer. Even thought the code is implemented in Python, it runs 3.9x faster than the original implementation in Fortran. This is due to the help of a domain-specific…
Just-DREAM-about-it: Figurative Language Understanding with DREAM-FLUTE
November 18, 2022 | Yuling GuFigurative language (e.g., "he flew like the wind") is challenging to understand, as it is hard to tell what implicit information is being conveyed from the surface form alone. We hypothesize that to perform this task well, the reader needs to mentally elaborate the scene being described to identify a sensible…
Towards Teachable Reasoning Systems: Using a Dynamic Memory of User Feedback for Continual System Improvement
November 16, 2022 | Bhavana Dalvi MishraEMNLP'22 talk for paper: https://www.semanticscholar.org/paper/Towards-Teachable-Reasoning-Systems%3A-Using-a-Memory-Dalvi-Tafjord/e7d75b80e0fa3ae190ff91676dbf18a006d3a311 Our goal is a teachable reasoning system for question-answering (QA), where a user can interact with faithful answer explanations, and…
