报告摘要:In thistalk, I will present several recent works of mine on constructing experimentaldesign for computer experiments. Computer experiments are computer programsthat simulate real systems using mathematical models. Some such simulations areextremely slow in computation, calling for experimental designs that areefficient in building surrogate models. Some recent work suggests thatspace-filling designs with low fill distance, high separation distance, andcertain projective properties are appealing for computer experiments. Usually,such designs are generated using global optimization techniques. However, becausethe optimization problem is fundamentally difficult, near optimal designs arerarely obtained. My approach is to use lattices that have distance propertiesin Euclidean space to construct space-filling designs. Such designs includerotated sphere packing designs and interleaved lattice-based designs.
