arXiv:2605.24803v1 Announce Type: new Abstract: A key goal in stochastic contextual linear bandits is to efficiently learn a near-optimal policy. Prior algorithms for this problem learn a policy by strategically sampling actions but naively (passively) sampling contexts from the underlying context distribution. However, in many practical scenarios -- including online content recommendation, survey research, and clinical trials -- practitioners can actively sample or recruit contexts based on prior knowledge of the context distribution. Despite this potential for active learning, the role of st
This research is published as AI systems become more complex and require more efficient learning strategies, especially in data-scarce or cost-sensitive environments.
Improving active learning in contextual bandits can significantly reduce the data and computational resources needed for effective AI policy learning, accelerating deployment in real-world applications.
The ability to actively sample contexts, rather than passively, provides AI systems with a more powerful exploration strategy, leading to faster convergence to optimal policies.
