An Optimal Preparation for Studying Optimization [PDF]

Neuron, 2000
Imagine a fly navigating through a forest at 2 m/s. In order to correct for the effects of the wind and other flight instabilities, the fly must continually estimate its heading direction if only to avoid running into a tree or inadvertently flying in circles. Given the striking prominence of eyes on a fly's body, it is not surprising that vision plays

Optimizing Bayesian optimization

, 2018
We are concerned primarily with improving the practical applicability of Bayesian optimization. We make contributions in three key areas. We develop an intuitive online stopping criterion, allowing only as many steps as necessary to achieve the desired target to be taken. By combining this with intelligent online switching between acquisition functions

Optimization

Journal of Research of the National Bureau of Standards, 1985
Most research and development projects require the optimization of a system response as a function of several experimental factors. Familiar chemical examples are the maximization of product yield as a function of reaction time and temperature; the maximization of analytical sensitivity of a wet chemical method as a function of reactant concentration ...
