In designing computer experiments,\nLatin hypercube designs (LHDs) are widely used. However, finding an optimal LHD\nis computationally cumbersome. On the other hand, although many optimal designs\nare well known for physical experiments, the redundancy of design points make\nthem undesirable for computer experiments. In this work, we present a new class\nof space-filling designs developed by splitting two-level full or fractional\nfactorial designs into multiple layers. The method takes advantages of many\navailable results in designing physical experiments and therefore, the proposed\nMulti-layer designs (MLDs) are easy to generate. Moreover, our numerical study\nshows that MLDs can have better space-filling properties than optimal LHDs.\u003C\/p\u003E\n\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\n\n\u003Cp\u003E3. \u003Cstrong\u003ETitle\u003C\/strong\u003E: Some\nNew Advances in Design and Modeling of Computer Experiments \u003C\/p\u003E\n\n\u003Cp\u003E\u003Cstrong\u003ESpeaker\u003C\/strong\u003E: Professor Peter Z.

Design and modeling are two key aspects of\ncomputer experiments. In this talk, I will report some recent advances in both\naspects. Specific topics include a new approach for emulation of computer\nmodels with qualitative and quantitative factors; sequential space-filling\ndesigns; Sudoku based space-filling designs; and sliced Latin hypercube designs\nfor ensembles of computer models.\u0026nbsp; \u003C\/p\u003E\n\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\n\n\u003Cp\u003E4. \u003Cstrong\u003ETitle\u003C\/strong\u003E: Analysis\nof Computer Experiments with Functional Response\u003C\/p\u003E\n\n\u003Cp\u003E\u0026nbsp;\u0026nbsp; \u003Cstrong\u003ESpeaker\u003C\/strong\u003E: Professor Ying Hung\u0026nbsp; (Statistics, Rutgers)\u003C\/p\u003E\n\n\u003Cp\u003E\u003Cstrong\u003EAbstract\u003C\/strong\u003E: Most existing methods for analyzing computer experiments\nwith single outputs such as kriging cannot be easily applied to functional\noutputs due to the computational problems caused by high-dimensionality of the\nresponse. In this paper, we develop an efficient implementation of kriging for\nanalyzing functional responses. Our methodology uses a two-stage model building\nprocedure with Kronecker products and an improved EM algorithm for estimation.\nThe methodology is illustrated using a computer experiment conducted for\noptimizing residual stresses in machined parts.
