Physics-informed learning and uncertainty quantification (July 1, 9:00 am)
Speaker: C. F. Jeff Wu, Chinese University of Hong Kong
Abstract: Suppose a system or product can be described by its underlying physical knowledge, usually via a set of partial differential equations (pde’s). Then the corresponding AI tools must be informed by this knowledge. In this talk I will focus on using physical knowledge to “inform” the development of statistical/machine learning. I will use two recent work to illustrate how this can be done. In developing the injector design for rocket propulsion, the mixing of oxygen and fuel was critical for the stability of propulsion. Navier-Stokes equations were used to describe the mixing behavior. However, the solution of the equations could take six weeks on clustered machine. Thus only a small number of numerical solutions could be performed. A surrogate model was instead developed by using tools in uncertainty quantification (UQ) and machine learning (ML). It could be computed within one hour and can mimic the mixing behavior. The success lies in using UQ-ML tools to incorporate known physical phenomena about mixing. The second work addresses the issue of incorporating knowledge of the pde’s such as its boundary conditions. In building an efficient surrogate model, it must also satisfy the same boundary conditions. We have constructed a new class of Gaussian process models that incorporate the same boundary information. We develop a framework of GP models based on stochastic partial differential equations (SPDEs) with Dirichlet or Robin boundary conditions. For fast computation, we use a kernel regression approximation to accurately approximate the SPDE covariances. Real examples are used for illustration.
Data Analytics and Optimization for Smart Industry (July 1, 10:20 am)
Speaker: Lixin Tang, Northeastern University
Abstract: Data analytics is the frontier basic research direction of industrial intelligence and one of the driving forces to promote scientific development. Systems optimization is the core basic theory of decision-making in smart industry, as well as the heart and engine of data analytics. This talk will discuss the fusion theory of data analytics and optimization (abbreviated as DAO) inspired by the structure of human brain, as well as the DAO-based octopus-topology solutions that we have been working on. Being related to industrial intelligence, the optimization part of DAO-based octopus-topology solutions include integer optimization, intelligent optimization, convex and sparse optimization, as well as topology and dynamic optimization; while the data analytics part consists of reinforcement learning, evolutionary learning, statistical physics-based learning and information theory-based learning. This talk will also introduce the applications of DAO theory in frontier systems technology, quality science, quality analytics and optimization, as well as production management. First, a frontier systems technology framework is constructed in a hierarchical structure, which consists of four levels, including perception, discovery, decision-making and execution from bottom to top, abbreviated as PDDE. Second, shifting the research perspective from macro production process to micro material, we discuss the material-based quality science on material discovery and synthesis, for quality analytics in manufacturing industries. Third, focusing on full lifecycle quality management of RDMS (Raw Material-Device - Machine - Systems), we consider the supply chain quality analytics and dynamic optimization, which covers the whole process of upstream steel production and downstream equipment manufacturing. Then, to facilitate the comprehensive quality improvement, a full-dimension organic management system is constructed as “Triple Transfer and One Feedback” framework. Based on that, production, logistics and energy across different manufacturing departments within an industrial enterprise are investigated. Finally, the ongoing research is generalized, which focuses on the systematic optimization and mechanism design of environment management, aiming to achieve overall carbon emission reduction for industrial ecosystem.
Deep Learning Enabled Modeling and Condition-Based Maintenance of Smart and Connected Systems (July 2, 9:00 am)
Speaker: Shiyu Zhou, University of Wisconsin Madison
Abstract: Due to the fast development of sensing and information technology, many modern engineering systems, such as manufacturing and logistics systems, have become data-rich. The unprecedented data availability, combined with ever-growing computational power, creates unprecedented opportunities for system modeling and decision-making. In this presentation, new deep learning enabled modeling approaches for system degradation will be introduced. The approach features an integration of deep neural networks and the classical hidden Markov structure. As a result, the proposed modeling approach has excellent interpretability, scalability, and flexibility. In addition, a condition-based maintenance strategy for a large-scale multiple-component system is presented. The advantageous features of the developed methods are demonstrated through numerical studies and real-world case studies. Thoughts on potential research opportunities exploiting the ever-growing data-rich engineering environment will be shared as well.
Singapore and Micron: At the Heart of Future Intelligence (Jul 2, 10:10 am)
Speaker: Joshua Lee, Micron Technology
Abstract: This keynote presentation explores the transformative impact of artificial intelligence (AI) on the semiconductor industry and advanced manufacturing. The address outlines how AI is reshaping global industries—from autonomous vehicles to smart factories—and highlights Micron’s strategic role in enabling this transformation through cutting-edge memory and storage technologies. The presentation details Micron’s global leadership in DRAM and NAND innovation, its AI Centers of Excellence, and its contributions to AI infrastructure across cloud and edge computing. It also showcases real-world AI applications within Micron, including smart warehousing, image analytics for defect detection, and generative AI for manufacturing optimization. Emphasis is placed on the exponential growth in memory and storage demand driven by AI workloads, and the company’s roadmap to meet these needs through advanced process nodes and high-performance products. Key enablers such as ecosystem collaboration, digital infrastructure, and talent development are discussed as critical to unlocking AI’s full potential. The keynote concludes with a call for cross-sector partnership to accelerate innovation and responsibly harness AI for global impact.
