Enhancing Learning with Noisy Labels via Rockafellian Relaxation

ICLR 2026poster

Labeling errors in datasets are common, arising in a variety of contexts, such as human labeling and weak labeling. Although neural networks (NNs) can tolerate modest amounts of these errors, their performance degrades substantially once the label error rate exceeds a certain threshold. We propose t…

Towards Understanding the Fragility of Multilingual LLMs against Fine-Tuning Attacks

NAACL 2025findings

Recent advancements in Large Language Models (LLMs) have sparked widespread concerns about their safety. Recent work demonstrates that safety alignment of LLMs can be easily removed by fine-tuning with a few adversarially chosen instruction-following examples, i.e., fine-tuning attacks. We take a fu…

Quantifying and Mitigating the Impact of Label Errors on Model Disparity Metrics

ICLR 2023poster

Errors in labels obtained via human annotation adversely affect a trained model's performance. Existing approaches propose ways to mitigate the effect of label error on a model's downstream accuracy, yet little is known about its impact on a model's group-based disparity metrics\footnote{Group-based…
