Advancing Social Intelligence in AI Agents: Technical Challenges and Open Questions

no code implementations17 Apr 2024 Leena Mathur, Paul Pu Liang, Louis-Philippe Morency

Building socially-intelligent AI agents (Social-AI) is a multidisciplinary, multimodal research goal that involves creating agents that can sense, perceive, reason about, learn from, and respond to affect, behavior, and cognition of other agents (human or artificial).

SOTOPIA: Interactive Evaluation for Social Intelligence in Language Agents

1 code implementation18 Oct 2023 Xuhui Zhou, Hao Zhu, Leena Mathur, Ruohong Zhang, Haofei Yu, Zhengyang Qi, Louis-Philippe Morency, Yonatan Bisk, Daniel Fried, Graham Neubig, Maarten Sap

We present SOTOPIA, an open-ended environment to simulate complex social interactions between artificial agents and evaluate their social intelligence.

Difference-Masking: Choosing What to Mask in Continued Pretraining

1 code implementation23 May 2023 Alex Wilf, Syeda Nahida Akter, Leena Mathur, Paul Pu Liang, Sheryl Mathew, Mengrou Shou, Eric Nyberg, Louis-Philippe Morency

The self-supervised objective of masking-and-predicting has led to promising performance gains on a variety of downstream tasks.

Expanding the Role of Affective Phenomena in Multimodal Interaction Research

no code implementations18 May 2023 Leena Mathur, Maja J Matarić, Louis-Philippe Morency

We find that this body of research has primarily focused on enabling machines to recognize and express affect and emotion.

Towards Intercultural Affect Recognition: Audio-Visual Affect Recognition in the Wild Across Six Cultures

no code implementations31 Jul 2022 Leena Mathur, Ralph Adolphs, Maja J Matarić

In our multicultural world, affect-aware AI systems that support humans need the ability to perceive affect across variations in emotion expression patterns across cultures.

Speech Representations and Phoneme Classification for Preserving the Endangered Language of Ladin

no code implementations27 Aug 2021 Zane Durante, Leena Mathur, Eric Ye, Sichong Zhao, Tejas Ramdas, Khalil Iskarous

To address this problem in the context of Ladin, our paper presents the first analysis of speech representations and machine learning models for classifying 32 phonemes of Ladin.

Affect-Aware Deep Belief Network Representations for Multimodal Unsupervised Deception Detection

no code implementations17 Aug 2021 Leena Mathur, Maja J Matarić

Our results motivate future work on unsupervised, affect-aware computational approaches for detecting deception and other social behaviors in the wild.

Deception Detection

Modeling User Empathy Elicited by a Robot Storyteller

1 code implementation29 Jul 2021 Leena Mathur, Micol Spitale, Hao Xi, Jieyun Li, Maja J Matarić

Our research informs and motivates future development of empathy perception models that can be leveraged by virtual and robotic agents during human-machine interactions.

Unsupervised Audio-Visual Subspace Alignment for High-Stakes Deception Detection

no code implementations6 Feb 2021 Leena Mathur, Maja J Matarić

Our subspace-alignment (SA) approach adapts audio-visual representations of deception in lab-controlled low-stakes scenarios to detect deception in real-world, high-stakes situations.

Introducing Representations of Facial Affect in Automated Multimodal Deception Detection

no code implementations31 Aug 2020 Leena Mathur, Maja J. Matarić

This approach achieved a higher AUC than existing automated machine learning approaches that used interpretable visual, vocal, and verbal features to detect deception in this dataset, but did not use facial affect.
