Resilience of Cyber-Physical Systems: Definition, Issues, Approaches, and Examples
Date: May 14, 2024, 8:45am-9:45am
Speaker: Kang G. Shin, The University of Michigan, USA
Chair: Chenyang Lu, Washington University in St. Louis
Abstract: I will first re-introduce the original concept of cyber-physical systems (CPSes), especially differentiating CPSes from other well-known systems such as embedded (real-time) systems, sensor networks, etc. I will then discuss how to characterize the resilience of CPSes, and present research challenges and possible approaches. Lastly, I will discuss several examples of resilient CPSes, including real-time control systems, battery management for transportation platforms, and secure in-vehicle communications, to illustrate how to deal with issues of CPS resilience.

From Wireless Sensors to Perceptual Networks
Date: May 15, 2024, 8:45am-9:45am
Speaker: Prabal Dutta, University of California, Berkeley, USA
Chair: Xiaofan (Fred) Jiang, Columbia University
Abstract: A quarter century ago, a set of MobiCom challenge papers catalyzed a research community to pursue the vision of wirelessly networked sensors of increasingly diminishing proportions that could densely monitor the physical world. Today, much of the original vision had been realized, and a bewildering array and variety of systems have been fielded that allow us to gather and process unprecedented amounts of data about the physical world. But this progress has also exposed many new challenges and opportunities. This talk will draw on my lab’s efforts in designing, deploying, and commercializing wireless sensors for a range of applications. The evolution of these efforts—from seemingly trivial connected sensors with simple cloud analytics to more complex networked sensors with sophiscated sensing and communications to sustainable perceptual networks that perform multi-spectral data fusion and inference at the edge to detect complex but sparse faults—has highlighted numerous exciting technical and methodological challenges ripe for attention from the research community.
Bio: Prabal Dutta is a Professor of Electrical Engineering and Computer Sciences at University of California, Berkeley.

AI for Health with Wearables
Date: May 16, 2024, 8:45am-9:45am
Speaker: Chenyang Lu, Washington University in St. Louis, USA
Chair: Tarek Abdelzaher, University of Illinois
Abstract: Artificial intelligence (AI) has emerged as a powerful tool for solving complex health problems using data-driven approaches. AI for health is fueled by both the advancement in AI methods and the availability of data provided by electronic health records (EHR) and wearables. This talk will explore the potential to support precision medicine using wearables that enable unobtrusive monitoring of patients in their daily lives. To harness the full potential of wearables, it is crucial to develop machine learning (ML) models to extract reliable clinical information from noisy and incomplete sensor data. Moreover, these ML approaches need to scale effectively across a wide range of sample sizes, providing robust predictions even with limited data, while enhancing predictive power with large datasets. We will highlight three clinical studies that use Fitbit wristbands as wearable instruments. First, we have established a robust feature engineering and ML pipeline specifically tailored for wearable studies with limited sample sizes. This pipeline demonstrated its effectiveness in predicting post-operative complications in a prospective clinical trial of patients undergoing pancreatic surgery. Second, we have developed WearNet, an end-to- end deep learning model designed to detect mental health disorders using wearable data. WearNet has been trained and validated on a large public dataset comprising 8,996 participants, including 1,247 diagnosed with mental disorders. Finally, we have explored multi-task ML approaches to predict individualized responses to depression therapy based on wearable data collected in a randomized controlled trial (RCT). By the end of the talk, we will discuss the opportunities and directions in the interdisciplinary field of AI and wearables for health, showcasing the transformative impact they can have on healthcare outcomes.
