arXiv:2311.07565v3 Announce Type: replace Abstract: We introduce exploration via linear loss perturbations (EVILL), a randomised exploration method for structured stochastic bandit problems that works by solving for the minimiser of a linearly perturbed regularised negative log-likelihood function. We show that, for the case of generalised linear bandits, EVILL reduces to perturbed history exploration (PHE), a method where exploration is done by training on randomly perturbed rewards. In doing so, we provide a simple and clean explanation of when and why random reward perturbations give rise t
This research provides a theoretical underpinning and unification for methods of exploration in stochastic bandit problems, occurring as AI development rapidly advances, requiring more robust and efficient learning algorithms.
A strategic reader should care because improved exploration methods like EVILL and PHE lead to more efficient and adaptable AI systems, enhancing their performance and applicability in real-world scenarios.
The understanding of how and why random reward perturbations enable effective exploration is now clearer, potentially accelerating the development of more sophisticated AI agents capable of learning in complex, unknown environments.
