Theory of Continual Learning Against Data Poisoning Attacks

arXiv:2606.29841v1 Announce Type: new Abstract: Continual learning (CL), where a model is trained on a sequence of data tasks, is increasingly being adopted across key fields such as large language models and image recognition, yet it remains highly vulnerable to data poisoning that triggers learning divergence or severe excess risk. Despite these threats, a principled theoretical foundation in CL for understanding attack and defense remains lacking. In this paper, we develop a theoretical framework to analyze strategic attacks and defenses in regularization-based CL, a cornerstone of recent C

Why this matters
Why now

The increasing adoption of continual learning in critical AI applications, such as large language models, necessitates a robust theoretical framework for understanding and mitigating emerging vulnerabilities like data poisoning.

Why it’s important

This research provides a foundational theoretical framework for analyzing and defending against data poisoning in continual learning, which is crucial for the reliability and trustworthiness of advanced AI systems.

What changes

The development of a principled theoretical foundation allows for the systematic analysis of attack and defense strategies against data poisoning in continual learning, moving beyond ad-hoc solutions.
