Continual Learning with Support Boundary Experience Blending

arXiv:2507.23534v3 Announce Type: replace Abstract: Continual learning (CL) seeks to mitigate catastrophic forgetting when models are trained with sequential tasks. A common approach, experience replay (ER), stores past exemplars but only sparsely approximates the data distribution, yielding fragile and oversimplified decision boundaries. We address this limitation by introducing Support Boundary Data (SBD), generated via differential-privacy-inspired noise into latent features to create boundary-adjacent representations that implicitly regularize decision boundaries. Building on this idea, we

Why this matters
Why now

The continuous evolution of AI models requires robust mechanisms to prevent catastrophic forgetting, making novel approaches to continual learning highly relevant.

Why it’s important

This research addresses a fundamental challenge in AI model development, potentially enabling more efficient and adaptable AI systems that learn continuously without losing past knowledge.

What changes

The proposed method offers a more stable and less fragile approach to experience replay in continual learning by explicitly regularizing decision boundaries.
