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.

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.

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.

Shape-CD: Change-Point Detection in Time-Series Data with Shapes and Neurons

no code implementations22 Jul 2020 Varsha Suresh, Wei Tsang Ooi

We found that existing approaches become less accurate when the underlying process is complex and generates large varieties of patterns in the time series.
