Workshop Details

Complex systems are prevalent in a wide range of scientific and engineering disciplines. These systems incorporate numerous variables, some of which are controllable, some are subject to design specifications, and others may be latent or determined by either identified or unidentified processes. Accurate prediction of the system response is intrinsically difficult, yet often secondary to more pressing engineering concerns regarding optimal design or control of the system. For instance, in the realm of electromagnetic (EM) devices, advancements in fabrication technologies have afforded extensive design and control freedoms, such as metamaterials and 4D materials. These developments have rendered simulation and optimization as the limiting factors for inverse design or control applications. In the context of corrosion science, the corrosion initiation of metals is governed by dynamic and complex processes that take place at multi-scale levels. As such, investigation of its kinetic dissolution with just macroscopic, or bulk, electrochemical techniques or sometimes with high resolution microscopy poses considerable challenges. Scientific AI offers a viable avenue for the rapid and reliable prediction and discovery during the initiation and propagation of metallic corrosion. The intersection of scientific AI and complex systems engenders a host of unresolved questions, including efficient simulation strategies, model parameterization, the integration of domain-specific knowledge or system architecture, and the role of AI in scientific computing for predictive and optimization purposes.

The methodologies of Scientific AI utilize the robust nonlinear fitting capabilities of deep learning to enhance the predictive efficiency and accuracy of conventional scientific computing and statistical methods for the simulation of complex systems. This workshop aims to explore how scientific AI employs domain-specific knowledge and scientific computational techniques to improve the accuracy and efficiency of the optimization of complex systems. It is essential to note that a scientific AI model proficient in making accurate predictions is not invariably well-suited for optimization tasks. Therefore, this workshop will concentrate on approaches that facilitate effective optimization performance of scientific AI, whether through gradient-based optimization techniques or alternative strategies, contributing to groundbreaking scientific and engineering discoveries through optimization.
