Large Language Models are Capable of Offering Cognitive Reappraisal, if Guided

1 code implementation1 Apr 2024 Hongli Zhan, Allen Zheng, Yoon Kyung Lee, Jina Suh, Junyi Jessy Li, Desmond C. Ong

Large language models (LLMs) have offered new opportunities for emotional support, and recent work has shown that they can produce empathic responses to people in distress.

Large Language Models Produce Responses Perceived to be Empathic

1 code implementation26 Mar 2024 Yoon Kyung Lee, Jina Suh, Hongli Zhan, Junyi Jessy Li, Desmond C. Ong

Large Language Models (LLMs) have demonstrated surprising performance on many tasks, including writing supportive messages that display empathy.

Evaluating Subjective Cognitive Appraisals of Emotions from Large Language Models

1 code implementation22 Oct 2023 Hongli Zhan, Desmond C. Ong, Junyi Jessy Li

The emotions we experience involve complex processes; besides physiological aspects, research in psychology has studied cognitive appraisals where people assess their situations subjectively, according to their own values (Scherer, 2005).

Using Positive Matching Contrastive Loss with Facial Action Units to mitigate bias in Facial Expression Recognition

no code implementations8 Mar 2023 Varsha Suresh, Desmond C. Ong

Machine learning models automatically learn discriminative features from the data, and are therefore susceptible to learn strongly-correlated biases, such as using protected attributes like gender and race.

ReaSCAN: Compositional Reasoning in Language Grounding

3 code implementations18 Sep 2021 Zhengxuan Wu, Elisa Kreiss, Desmond C. Ong, Christopher Potts

The ability to compositionally map language to referents, relations, and actions is an essential component of language understanding.

Using Knowledge-Embedded Attention to Augment Pre-trained Language Models for Fine-Grained Emotion Recognition

1 code implementation31 Jul 2021 Varsha Suresh, Desmond C. Ong

Modern emotion recognition systems are trained to recognize only a small set of emotions, and hence fail to capture the broad spectrum of emotions people experience and express in daily life.

An Ethical Framework for Guiding the Development of Affectively-Aware Artificial Intelligence

no code implementations29 Jul 2021 Desmond C. Ong

We propose a multi-stakeholder analysis framework that separates the ethical responsibilities of AI Developers vis-\`a-vis the entities that deploy such AI -- which we term Operators.

Critically examining the Domain Generalizability of Facial Expression Recognition models

no code implementations29 Jun 2021 Varsha Suresh, Gerard Yeo, Desmond C. Ong

Using a state-of-the-art model with twelve datasets (six collected in-lab and six ``in-the-wild"), we conduct extensive round-robin-style experiments to evaluate classification accuracies when given new data from an unseen dataset.

On Explaining Your Explanations of BERT: An Empirical Study with Sequence Classification

2 code implementations1 Jan 2021 Zhengxuan Wu, Desmond C. Ong

In this paper, we adapt existing attribution methods on explaining decision makings of BERT in sequence classification tasks.

Structured Self-Attention Weights Encode Semantics in Sentiment Analysis

1 code implementation10 Oct 2020 Zhengxuan Wu, Thanh-Son Nguyen, Desmond C. Ong

Very recent work suggests that the self-attention in the Transformer encodes syntactic information; Here, we show that self-attention scores encode semantics by considering sentiment analysis tasks.

Robot Capability and Intention in Trust-based Decisions across Tasks

no code implementations3 Sep 2019 Yaqi Xie, Indu P Bodala, Desmond C. Ong, David Hsu, Harold Soh

In this paper, we present results from a human-subject study designed to explore two facets of human mental models of robots---inferred capability and intention---and their relationship to overall trust and eventual decisions.

Applying Probabilistic Programming to Affective Computing

1 code implementation15 Mar 2019 Desmond C. Ong, Harold Soh, Jamil Zaki, Noah D. Goodman

Affective Computing is a rapidly growing field spurred by advancements in artificial intelligence, but often, held back by the inability to translate psychological theories of emotion into tractable computational models.
