Bayesian optimization is a sequential design strategy for global optimization of black-box functions that does not assume any functional forms. It is usually employed to optimize expensive-to-evaluate functions. Meer weergeven The term is generally attributed to Jonas Mockus [lt] and is coined in his work from a series of publications on global optimization in the 1970s and 1980s. Meer weergeven Examples of acquisition functions include • probability of improvement • expected improvement • Bayesian expected losses • upper confidence bounds (UCB) or lower confidence bounds Meer weergeven The approach has been applied to solve a wide range of problems, including learning to rank, computer graphics and visual design, robotics, sensor networks, automatic … Meer weergeven Bayesian optimization is typically used on problems of the form $${\textstyle \max _{x\in A}f(x)}$$, where $${\textstyle A}$$ is a set of points, $${\textstyle x}$$, which rely upon … Meer weergeven The maximum of the acquisition function is typically found by resorting to discretization or by means of an auxiliary optimizer. Acquisition functions are typically well-behaved and are maximized using a numerical optimization technique, such as Meer weergeven • Multi-armed bandit • Kriging • Thompson sampling • Global optimization • Bayesian experimental design Meer weergeven WebMachine learning (ML) is a field devoted to understanding and building methods that let machines "learn" – that is, methods that leverage data to improve computer …
