New Bayesian Optimization Algorithms Tailored for Probability Simplex

Researchers have developed a new family of Bayesian optimization algorithms, termed \"$\alpha$-GaBO\", specifically designed for optimizing functions over the probability simplex. This novel approach leverages information geometry to construct Matérn kernels and acquisition function optimizers that respect the simplex's non-Euclidean geometry. The method has demonstrated superior performance compared to traditional constrained Euclidean approaches in various applications, including component mixtures, classifier mixtures, and robotic control tasks.
