Researchers have developed a new Bayesian optimization framework designed to improve hyperparameter tuning in stochastic models. This method uses a statistical surrogate for random variables, allowing for analytical evaluation of expectation operators. The framework also provides a closed-form expression for optimizing the random acquisition function, significantly reducing computational costs. Experiments show this approach uses approximately 40 times less data than Monte Carlo methods and is an order of magnitude more efficient than Gaussian process-based Bayesian optimization. AI
