arXiv:2607.00144v1 Announce Type: cross Abstract: Active learning (AL) performance is known to be budget-dependent, yet regimes are typically defined by heuristic label counts that fail to generalize across datasets or architectures. We characterize AL dynamics by reframing budget regimes as shifts in the dominant generalization mechanism. By reinterpreting PAC-style risk components as dynamic interacting terms, we prove that dominance shifts are structurally unavoidable, creating a moving bottleneck for generalization. We operationalize this using measurable proxies and a segmented regression
This paper offers a theoretical advancement in understanding active learning dynamics, arriving as AI research continuously seeks more efficient and data-scarce training methods.
A deeper, mechanism-driven understanding of active learning performance could significantly improve AI model development efficiency and resource allocation, particularly in data-limited scenarios.
The definition of effective 'budget regimes' in active learning shifts from heuristic label counts to a more principled, mechanism-driven classification based on generalization bottlenecks.

More robust and efficient active learning algorithms will emerge from this theoretical framework.
This could lead to a reduction in the sheer volume of labeled data required for certain AI applications, streamlining development cycles.
Improved active learning might accelerate the deployment of AI in domains where data annotation is expensive or scarce, expanding AI's reach.
