讲座内容简介：

AI/machine learning places significant roles on data-driven modelling of complex systems. This is typically accomplished through the utilization of machine learning algorithms or system identification techniques, relying on either input and output data or solely output data from the concerned system. Many methodologies for data-driven modelling have been developed, including NN (Neural Networks), LSTM (Long-Short Term Memory) networks, etc. These contemporary methodologies have found extensive applications in tackling challenges in engineering systems design, control, condition monitoring, and characterization, primarily because of their impressive predictive and classification capabilities. However, applying a pure machine learning model in relevant engineering applications is just like a tightrope walking. The black-box nature of these models makes it challenging to place trust in them. In this talk, I will introduce the unique NARX (Nonlinear Autoregressive models with Exogenous Input) modelling and nonlinear frequency analysis methodologies I have developed since my PhD at the University of Sheffield. The research outcomes facilitate the application of physically interpretable machine learning in condition monitoring and engineering systems design. These involve (i) Condition monitoring of machining cutting tools, and (ii) Digital design of complex dynamic materials. The proposed analysis and design framework can be applied to resolve a wide range of dynamic problems in engineering practice.
