Understanding and Mitigating Human-Labelling Errors in Supervised Contrastive Learning

no code implementations10 Mar 2024 Zijun Long, Lipeng Zhuang, George Killick, Richard McCreadie, Gerardo Aragon Camarasa, Paul Henderson

In this paper, we show that human-labelling errors not only differ significantly from synthetic label errors, but also pose unique challenges in SCL, different to those in traditional supervised learning methods.

CLCE: An Approach to Refining Cross-Entropy and Contrastive Learning for Optimized Learning Fusion

no code implementations22 Feb 2024 Zijun Long, George Killick, Lipeng Zhuang, Gerardo Aragon-Camarasa, Zaiqiao Meng, Richard McCreadie

State-of-the-art pre-trained image models predominantly adopt a two-stage approach: initial unsupervised pre-training on large-scale datasets followed by task-specific fine-tuning using Cross-Entropy loss~(CE).

Elucidating and Overcoming the Challenges of Label Noise in Supervised Contrastive Learning

no code implementations25 Nov 2023 Zijun Long, George Killick, Lipeng Zhuang, Richard McCreadie, Gerardo Aragon Camarasa, Paul Henderson

However, while the detrimental effects of noisy labels in supervised learning are well-researched, their influence on SCL remains largely unexplored.
