arXiv:2510.03839v2 Announce Type: replace Abstract: We present a theoretical framework for M-FISHER, a method for sequential distribution shift detection and stable adaptation in streaming data. For detection, we construct an exponential martingale from non-conformity scores and apply Ville's inequality to obtain time-uniform guarantees on false alarm control, ensuring statistical validity at any stopping time. Under sustained shifts, we further bound the expected detection delay as $\mathcal{O}(\log(1/\delta)/\Gamma)$, where $\Gamma$ reflects the post-shift information gain, thereby linking d
The paper presents a theoretical framework for M-FISHER, a new method to address a critical challenge in AI: sequential distribution shift detection and stable adaptation in streaming data. This development is timely given the increasing deployment of AI systems in dynamic, real-world environments where data distributions are constantly changing.
This research provides a statistically robust method for AI models to detect and adapt to real-time changes in their operating environment, ensuring continued reliability and performance. This is crucial for high-stakes applications where model degradation due to data drift can have significant consequences.
AI systems gain a more reliable and theoretically grounded mechanism for self-correction and adaptation in streaming data, moving beyond ad-hoc solutions for distribution shifts. This enhances the robustness and trustworthiness of AI deployments.
