Scalarizing Functions in Bayesian Multiobjective Optimization

Scalarizing functions have been widely used to convert a multiobjective optimization problem into a single objective optimization problem. However, their use in solving (computationally) expensive multi- and many-objective optimization problems in Bayesian multiobjective optimization is scarce. Scalarizing functions can play a crucial role on the quality and number of evaluations required when doing the optimization. In this article, we study and review 15 different scalarizing functions in the framework of Bayesian multiobjective optimization and build Gaussian process models (as surrogates, metamodels or emulators) on them. We use expected improvement as infill criterion (or acquisition function) to update the models. In particular, we compare different scalarizing functions and analyze their performance on several benchmark problems with different number of objectives to be optimized. The review and experiments on different functions provide useful insights when using and selecting a scalarizing function when using a Bayesian multiobjective optimization method

Effects of Gamification on Speed and Accuracy on an Interdependent Paper Sorting Task

This study examined the effects of gamification, i.e. (what makes games challenging, engaging and fun), and its effects on speed and accuracy on an interdependent paper sorting task. Undergraduate students (N=42) at the University of Central Florida participated by working interdependently in groups to sort numbered pieces of paper into piles before and after either playing video games or doing back-to-back drawing(basic team building exercises). It was hypothesized that participants who played video games would sort pieces of paper into the piles faster and more accurate than those who did back-to-back team exercises. Results showed that playing video games was not better than doing basic team exercises, but that the two tasks were relatively equal. Although groups were formed and dissolved quickly, there was improvement between the pre and posttests. While the experiment did not yield significant results, it is possible that using different video games or different interdependent tasks could foster increases in speed and accuracy compared to back-to-back drawing

What is “Making Good Trouble?” Well, for Meredith, it’s doing little things that you’re “not supposed to do” but aren’t wrong either. It’s taking every paint sample in the hardware store, carrying around a rubber dinosaur with you everywhere you go, having rainbow jell-o for breakfast, etc. “Making good trouble” is sticking up for what you believe in. For Meredith, that means advocating to save the US Postal Service and challenging what fine art in academia is. Making good trouble means sticking up for others, no matter what ethnicity, gender, sexuality, age, religion, or economic status a person has
