Combining Hyperband and Bayesian Optimization
Proper hyperparameter optimization is computationally very costly for expensive machine learning methods, such as deep neural networks; the same holds true for neural architecture search. Recently, the bandit-based strategy Hyperband has shown superior performance to vanilla Bayesian optimization methods that are limited to the traditional problem formulation of expensive blackbox optimization....
متن کاملA Lipschitz Exploration-Exploitation Scheme for Bayesian Optimization
The problem of optimizing unknown costly-to-evaluate functions has been studied extensively in the context of Bayesian optimization. Algorithms in this field aim to find the optimizer of the function by requesting only a few function evaluations at carefully selected locations. An ideal algorithm should maintain a perfect balance between exploration (probing unexplored areas) and exploitation (...
متن کاملSimplicial Lipschitz optimization without the Lipschitz constant
In this paper we propose a new simplicial partition-based deterministic algorithm for global optimization of Lipschitz-continuous functions without requiring any knowledge of the Lipschitz constant. Our algorithm is motivated by the well-known Direct algorithm which evaluates the objective function on a set of points that tries to cover the most promising subregions of the feasible region. Almo...
متن کاملGlobal optimization of Lipschitz functions
The goal of the paper is to design sequential strategies which lead to efficient optimization of an unknown function under the only assumption that it has a finite Lipschitz constant. We first identify sufficient conditions for the consistency of generic sequential algorithms and formulate the expected minimax rate for their performance. We introduce and analyze a first algorithm called LIPO wh...
