PFNs4BO sampler

In-context learning for Bayesian optimization. This sampler uses Prior-data Fitted Networks (PFNs) as a surrogate model for Bayesian optimization.

HEBO (Heteroscedastic and Evolutionary Bayesian Optimisation)

HEBO addresses the problem of noisy and heterogeneous objective functions by using a heteroscedastic Gaussian process and an evolutionary algorithm.
