Ankit Malviya, Sayak Dhole, Chandresh Kumar Maurya

Abstract: Highlights•We propose a novel UCL framework with zero forgetting, without a replay buffer.•Our approach incorporate cross-level instance-to-pseudo-instance discrimination into contrastive learning.•Our extensive experiments across standard datasets demonstrate performance improvements.
