arXiv:2605.25678v1 Announce Type: cross Abstract: We study the problem of multiclass PAC learning with bandit feedback in the realizable setting. In this framework, there is an unknown data distribution over an instance space $\mathcal{X}$ and a label space $\mathcal{Y}$, as in classical multiclass PAC learning, but the learner does not observe the labels of the i.i.d. training examples. Instead, in each round, it receives an unlabeled instance, predicts its label, and receives bandit feedback indicating only whether the prediction is correct. Despite this restriction, the goal remains the sam
This paper addresses fundamental theoretical sample complexity in PAC learning with bandit feedback, building on recent advances in AI and machine learning that push the boundaries of data efficiency and autonomous learning paradigms.
Improved theoretical understanding of PAC learning with bandit feedback has direct implications for developing more efficient and robust AI systems, especially in scenarios where labeled data is scarce or expensive, making AI deployment more feasible across diverse applications.
The theoretical framework for learning under partial feedback is becoming sharper, potentially leading to the development of algorithms that require significantly less human supervision during training, thereby accelerating AI development and deployment cycles.

More data-efficient AI models will emerge, reducing the computational and data labeling burden for AI development.
This could accelerate the development of more truly autonomous AI agents capable of learning effectively from limited interaction, furthering the 'AI Agents' narrative.
