Theoretical Foundations of Continual Learning via Drift-Plus-Penalty

arXiv:2606.08452v1 Announce Type: new Abstract: In many real-world settings, data streams are nonstationary and arrive sequentially, requiring learning systems to adapt continuously without retraining from scratch. Continual learning (CL) addresses this challenge by incorporating new tasks while mitigating catastrophic forgetting, where learning new information degrades performance on previously acquired knowledge. We introduce a control-theoretic perspective on CL that explicitly regulates the evolution of forgetting, framing adaptation as a controlled process subject to long-term stability c

Why this matters
Why now

The increasing complexity and continuous deployment of AI systems necessitate better methods for adaptation without catastrophic forgetting, driving new theoretical approaches like drift-plus-penalty.

Why it’s important

Continual learning is fundamental for developing robust, adaptable AI that can operate in dynamic real-world environments, directly impacting the viability of advanced AI applications.

What changes

This theoretical advancement could lead to more stable and efficient continual learning algorithms, reducing retraining costs and enabling longer-lived AI models.
