New method accelerates Thompson sampling for decision-making under uncertainty

Researchers have developed a novel approach to accelerate Thompson sampling, a common strategy for sequential decision-making under uncertainty. This new method amortizes the optimization process ahead of time, allowing for immediate approximations of the Thompson sampling distribution once observations are available. The technique is demonstrated on simulator-based design problems in synthetic biology and also enables efficient estimation of expected information gain, which can be used to select more informative samples or optimize designs. By combining this with immediate regret, the approach supports information-directed sampling, potentially outperforming standard Thompson sampling. AI
