New Epistemic Nearest Neighbors method speeds up Bayesian optimization

Researchers have developed Epistemic Nearest Neighbors (ENN), a novel method designed to improve the scalability of Bayesian optimization (BO) for problems with numerous observations. Unlike traditional Gaussian processes (GPs) that face cubic scaling issues with data size, ENN offers a linear scaling approach for both fitting and acquisition. This new method, integrated into the TuRBO-ENN framework, significantly reduces proposal times, achieving one to two orders of magnitude improvement over existing methods when handling up to 50,000 observations.
