WebThis paper presents the results and insights from the black-box optimization (BBO) chal- lenge at NeurIPS 2024 which ran from July{October, 2024. The challenge emphasized the importance of evaluating derivative-free optimizers for tuning the hyperparameters of ma- chine learning models. WebIn this paper, we propose a new class of algorithms, called Robust Blackbox Optimization (RBO). Remarkably, even if up to 23% of all the measurements are arbitrarily corrupted, RBO can provably recover gradients to high accuracy. RBO relies on learning gradient ﬂows using robust regression methods to enable off-policy updates. WebDerivative free global optimisation of CFD simulations . × ... Download Free PDF. ...
