报告摘要🤾🏽：In this talk, I will present several recent works of mine on constructing experimental design for computer experiments. Computer experiments are computer programs that simulate real systems using mathematical models. Some such simulations are extremely slow in computation, calling for experimental designs that are efficient in building surrogate models. Some recent work suggests that space-filling designs with low fill distance, high separation distance, and certain projective properties are appealing for computer experiments. Usually, such designs are generated using global optimization techniques. However, because the optimization problem is fundamentally difficult, near optimal designs are rarely obtained. My approach is to use lattices that have distance properties in Euclidean space to construct space-filling designs. Such designs include rotated sphere packing designs and interleaved lattice-based designs.
