Unsupervised Continual Clustering via Forward-Backward Knowledge Distillation

arXiv:2606.07474v1 Announce Type: new Abstract: Unsupervised Continual Learning (UCL) aims to enable neural networks to learn sequential tasks without labels or access to past data. A major challenge in this setting is Catastrophic Forgetting, where models forget previously learned tasks upon learning new ones. This challenge is amplified in UCL due to the absence of labels to guide learning and memory retention. Existing mitigation strategies, such as knowledge distillation and replay buffers, often raise memory and privacy concerns. Moreover, current UCL methods largely overlook clustering-s

Why this matters
Why now

The increasing complexity of AI models and the demand for continuous learning in dynamic environments without constant re-training highlight the immediate need for advanced unsupervised learning techniques.

Why it’s important

Overcoming catastrophic forgetting in unsupervised continual learning is crucial for developing robust, scalable, and adaptable AI systems, particularly in scenarios where data labeling is impractical or impossible.
