报告题目:Bayesian Optimization of Expected Quadratic Loss for Multiresponse Computer Experiments with Internal Noise

报告所属学科:管理科学与工程

报告人:Matthias HY Tan(香港城市大学)

报告摘要:

Design of systems based on computer simulations is prevalent. An important idea to improve design quality, called robust parameter design (RPD), is to optimize control factors based on the expectation of a loss function so that the design is robust to noise factor variations. When computer simulations are time consuming, optimizing the simulator based on a Gaussian process (GP) emulator for the response is a computationally efficient approach. For this purpose, acquisition functions (AFs) are used to sequentially determine the next design point so that the GP emulator can more accurately locate the optimal setting. Despite this, few articles consider AFs for positive definite quadratic forms such as the expected quadratic loss (EQL) function, which is the standard expected loss function for RPD with nominally-the-best responses. This paper proposes new AFs for optimizing the EQL, analyzes their convergence, and develops quick and accurate methods based on the characteristic function of the EQL to compute them. We apply the AFs to RPD problems with internal noise factors based on a GP model and an initial design tailored for such problems. Numerical results indicate that all four AFs considered have similar performance, and they outperform an optimization approach based on modeling the quadratic loss as a GP and maximin Latin hypercube designs.

报告题目:高速输流管道双稳态非线性动力学

报 告 人:丁虎 研究员(上海大学)

报告时间:2021年7月3日(周六)10:30

报告地点:明故宫校区A18-1109会议室

主办单位:机械结构力学及控制国家重点实验室、科协、航空学院、航空航天交叉研究院

报告内容摘要:

高速输液管道是民生、国防工程系统中的基础核心构件。在工程系统的运行过程中,管道总是伴随着有害的、非预期的、甚至会导致灾难性后果的共振,而高速流动会显著影响管道的动力学特征、恶化振动环境。管道的超临界高速失稳振动是本质非线性的,难以建立失稳后的动力学模型,而且系统的解不能通过线性派生系统逼近,其复杂的动力学行为有待揭示。近年来,主要关注于揭示超临界高速输流管道的非线性振动规律,目标是揭示工程中高速输流管道更容易振动破坏的动力学机理。并将理论研究成果应用于拓宽振动能采集的频带范围、排除工程中高速输流管道的振动破坏故障。

报告摘要:

Based on a decade-long research, Professor Huaichuan Rui will analyse the historical evolution of the Chinese high-speed train (HST) industry in the broad context of the global railway industry and political economy. She will present research findings related to the following questions: Why did foreign built railways dominate China after the 1870s? Why did China initiate high-speed rail development in 1990 and why was the initiative delayed for 18 years by Maglev proponents and others? How did China achieve successful technology transfer in manufacturing HSTs from multinational firms between 2004-2008? How did China develop HSTs with standards and IPRs between 2008-2015? and, to what extent have the Chinese HSTs succeeded in international markets?

报告人简介:

Professor Huaichuan Rui is Professor of International Business at the School of Business and Management, Royal Holloway, University of London. She received her PhD from the Judge Business School, University of Cambridge in 2003. She has been leading a pioneering project entitled 'Chinese outward investment and multinational enterprises (MNEs)' since 2005, conducting over 800 interviews around the world and gauging local views and reactions on Chinese MNEs. She has recently worked on an ERC (European Research Council) funded project entitled 'Trust, Global Traders, and Commodities in a Chinese International City', exploring the role played by the city of Yiwu in the global trade in low-grade Chinese commodities. Professor Rui has been invited by various institutions including the United Nations and OECD to speak about China's investment, trade, multinationals and development experience.
