Researchers have introduced a new method to localize the eluder dimension, a concept crucial for understanding the sample complexity of optimistic exploration in machine learning. This technique establishes a lower bound for generalized linear model classes, demonstrating that traditional eluder dimension analysis is insufficient for achieving first-order regret bounds. The proposed localization method not only recovers and enhances existing results for Bernoulli bandits but also provides the first genuine first-order bounds for finite-horizon reinforcement learning tasks with bounded cumulative returns.
