Time-Varying Gaussian Process Bandits with Unknown Prior

2024-02-02 · Juliusz Ziomek, Masaki Adachi, Michael A. Osborne

Bayesian optimisation requires fitting a Gaussian process model, which in turn requires specifying prior on the unknown black-box function -- most of the theoretical literature assumes this prior is known. However, it is…

Beyond Expected Return: Accounting for Policy Reproducibility when Evaluating Reinforcement Learning Algorithms

2023-12-12 · Manon Flageat, Bryan Lim, Antoine Cully

Many applications in Reinforcement Learning (RL) usually have noise or stochasticity present in the environment. Beyond their impact on learning, these uncertainties lead the exact same policy to perform differently, i.e…
