Jörg 29 Report post Posted June 29, 2017 Here are two posts that are related to surrogate-based optimization in CAESES: How to create a response surface in 4 easy steps Global optimization using response surfaces The first topic is about re-using an existing data base to quickly set up and use a response surface model. In the example, several different models (kriging, neural network, polynomial functions etc.) are created and the one with the best fit (checked through cross-validation) is taken for the evaluation. The second blog post is about automated shape optimization with CAESES. In the first stage, you create a small set of samples (e.g. through a Latin Hypercube Sampling) which is used for generating the response surface. Based on this model, a global optimization (genetic algorithm etc) can be run efficiently. The integrated charts also visualizes things such as the Pareto frontier.

Britton Ward 0 Report post Posted February 15, 2018 Joerg. This is an interesting blog post that has some application for me. Is there a tutorial project for this? Where can I get the Response Surface feature? Britt Share this post Link to post Share on other sites

Mr. RICHARD ADJEI 0 Report post Posted April 2, 2018 Hi CAESES Team, Please ill like to confirm something. For the Surrogate model in Dakota for SBGO, I see 2 types # Gaussian_process surf pack and Neural network.Please, 1. Are these two used to generate the response and the one that best fits is taken for evaluation or ?2. There is a single default model used in CAESES SBGO ? Thanks a lot. Cheers.

Jörg 29 Report post Posted April 3, 2018 Hi Richard, The default setting is the Gaussian process. The Neural Network is an alternative that you can also use: Share this post Link to post Share on other sites
