arXiv:2601.15036v4 Announce Type: replace Abstract: Factorizable joint shift (FJS) represents a type of distribution shift (or dataset shift) that comprises both covariate and label shift. Recently, it has been observed that FJS actually arises from consecutive label and covariate (or vice versa) shifts. Research into FJS so far has been confined mostly to the case of categorical labels. We propose a framework for analysing distribution shift in the case of a general label space, thus covering both classification and regression models. Based on the framework, we generalise existing results on
This work builds on recent observations regarding Factorizable Joint Shift, indicating a continued push to refine theoretical understandings of distribution shift in AI models.
Improved theoretical frameworks for distribution shift are crucial for developing more robust and generalizable AI, impacting reliability and applicability across various domains.
The proposed framework extends the analysis of Factorizable Joint Shift to general label spaces, enabling more comprehensive handling of both classification and regression scenarios.

More robust and generalizable AI models can be developed with a better understanding of distribution shifts.
This could lead to increased adoption of AI in critical applications where reliability is paramount, such as autonomous systems or medical diagnostics.
A fundamental advancement in handling distribution shifts might accelerate the development of more advanced AI agents capable of continuous learning in dynamic environments.
