Researchers have developed DeltaBO, a novel algorithm for Bayesian optimization that accelerates the process by transferring knowledge from related source tasks. This method builds on uncertainty quantification of the difference between source and target functions, offering theoretical guarantees and improved regret bounds compared to existing approaches. Empirical results demonstrate DeltaBO's effectiveness in hyperparameter tuning and synthetic function optimization. Separately, NUBO, a transparent Python package for Bayesian optimization, has been released, designed for ease of use across disciplines and supporting various optimization scenarios. AI
