Effects of Human Adversarial and Affable Samples on BERT Generalization

no code implementations12 Oct 2023 Aparna Elangovan, Jiayuan He, Yuan Li, Karin Verspoor

BERT-based models have had strong performance on leaderboards, yet have been demonstrably worse in real-world settings requiring generalization.

A Survey on Class Imbalance in Federated Learning

no code implementations21 Mar 2023 Jing Zhang, Chuanwen Li, Jianzgong Qi, Jiayuan He

We first introduce various types of class imbalance in federated learning, after which we review existing methods for estimating the extent of class imbalance without the need of knowing the actual data to preserve data privacy.

Beyond Just Vision: A Review on Self-Supervised Representation Learning on Multimodal and Temporal Data

no code implementations6 Jun 2022 Shohreh Deldari, Hao Xue, Aaqib Saeed, Jiayuan He, Daniel V. Smith, Flora D. Salim

Unlike existing reviews of SSRL that have pre-dominately focused upon methods in the fields of CV or NLP for a single modality, we aim to provide the first comprehensive review of multimodal self-supervised learning methods for temporal data.
