Large Language Models Meet Extreme Multi-label Classification: Scaling and Multi-modal Framework

AAAI 2026technical

Foundation models have revolutionized artificial intelligence across numerous domains, yet their transformative potential remains largely untapped in Extreme Multi-label Classification (XMC). Queries in XMC are associated with relevant labels from extremely large label spaces, where it is critical t

Prototypical Extreme Multi-label Classification with a Dynamic Margin Loss

NAACL 2025long

Extreme Multi-label Classification (XMC) methods predict relevant labels for a given query in an extremely large label space. Recent works in XMC address this problem using deep encoders that project text descriptions to an embedding space suitable for recovering the closest labels. However, learnin…

Multi-Objective Interpolation Training for Robustness To Label Noise

CVPR 2021poster

Deep neural networks trained with standard cross-entropy loss memorize noisy labels, which degrades their performance. Most research to mitigate this memorization proposes new robust classification loss functions. Conversely, we propose a Multi-Objective Interpolation Training (MOIT) approach that j…

Unsupervised Contrastive Learning of Sound Event Representations

ICASSP 2021accepted

Self-supervised representation learning can mitigate the limitations in recognition tasks with few manually labeled data but abundant unlabeled data—a common scenario in sound event research. In this work, we explore unsupervised contrastive learning as a way to learn sound event representations. To…

Unsupervised Label Noise Modeling and Loss Correction

ICML 2019oral

Despite being robust to small amounts of label noise, convolutional neural networks trained with stochastic gradient methods have been shown to easily fit random labels. When there are a mixture of correct and mislabelled targets, networks tend to fit the former before the latter. This suggests usin…
