【新时代物流沙龙第58期】adaptive sampling-based nonconvex and nonsmooth approaches for stochastic programs with implicitly decision-dependent uncertainty
时间:2024年11月14日(周四) 10:30-12:00 地点:思源东楼611 报告人简介:刘俊驿,清华大学工业工程系准聘副教授。2019年于美国南加州大学获得工业与系统工程博士学位。2023年入选国家级青年人才项目。目前研究方向为随机优化,侧重随机优化与统计、机器学习的交叉研究。以第一作者身份在operations research, mathematics of operations research, siam journal on optimization 等国际学术期刊上发表多篇文章。 报告摘要:we consider a class of stochastic programming problems where the implicitly decision-dependent random variable follows a nonparametric regression model with heteroskedastic error. to deal with the computational difficulty resulted from the latent decision dependency, we develop an adaptive sampling-based surrogate method that integrates the simulation scheme and statistical estimates in a way that the simulation process is adaptively guided by the algorithmic procedure.
