CLIMB: Centroid-Based Hierarchical Memory for Online Continual Self-Supervised Learning

arXiv:2606.31275v1 Announce Type: cross Abstract: Online Continual Self-Supervised Learning (OCSSL) aims to learn representations from a continuous stream of unlabeled data, without knowledge of task boundaries and under memory constraints. Existing methods rely either on replay buffers that exploit latent space structure, or on regularization alone. We present CLIMB (Continual Learning with Intelligent Memory Bank), which combines both simultaneously. Our method introduces a hierarchical centroid-based memory, bounded in total number of stored images, combined with knowledge distillation on r

Why this matters
Why now

The continuous growth of unsupervised data streams and the constraints of existing online learning methods necessitate more efficient and scalable self-supervised learning architectures.

Why it’s important

Improving online continual self-supervised learning can significantly enhance AI model adaptability and efficiency, particularly in real-world scenarios with dynamic, unlabeled data and memory limitations.

What changes

This paper presents a novel approach combining hierarchical memory and knowledge distillation, potentially leading to more robust and scalable AI systems capable of learning continuously without catastrophic forgetting.
