You can display a sample of the training images using the following code. figure; idx = randperm(numel(YTrain),20);fori = 1:numel(idx) subplot(4,5,i); imshow(XTrain(:,:,:,idx(i)));end Choose Variables to Optimize Choose which variables to optimize using Bayesian optimization, and ...
Specify a list of hyperparameters to optimize by using the OptimizeHyperparameters name-value argument, and specify optimization options by using the HyperparameterOptimizationOptions name-value argument. Specify 'OptimizeHyperparameters' as 'auto'. The 'auto' option includes a typical set of hyper...
Bayesian optimization (BO) is an indispensable tool to optimize objective functions that either do not have known functional forms or are expensive to evaluate. Currently, optimal experimental design is always conducted within the workflow of BO leading to more efficient exploration of the design space...

Laser wakefield accelerators promise to revolutionize many areas of accelerator science. However, one of the greatest challenges to their widespread adoption is the difficulty in control and optimization of the accelerator outputs due to coupling between
This MATLAB function resumes the optimization that produced results with additional options specified by one or more name-value arguments.
Bayesian optimization is an efficient global optimization approach. By using a Gaussian process regression, a surrogate model of the "black-box" code is constructed. It can be updated simultaneously whenever new simulation results are acquired. With predictions via the surrogate model, upcoming ...
