Location: Dana 442 Seminar Title: A More Resilient Power Grid with Faster-Than-Real-Time Stability Abstract: Since the northeast blackout of 1965, cascading blackouts have continued to happen on power grids in the North America and other countries. For a grid operator, it is vitally important to be aware of real-time stability and reliability margin for the current grid state under possible disturbances. However, a real-world power grid is an extremely complex, nonlinear network system. For instance, the bulk electric system of…

ECE Seminar: Deployable Learning Machines: From cost-to-go estimation to certification Michael Everett Location: 442 Dana and Zoom Link Abstract: Autonomous robots have the potential to transform our everyday lives, yet most of these systems struggle outside of the lab or carefully designed warehouses. This talk will first describe our work toward a new generation of robots that learn to handle the highly dynamic and uncertain nature of human environments. In particular, I will highlight the importance of obtaining accurate cost-to-go…

ECE Seminar: Autonomous Microsystems Based on Heterogeneously Integrated CMOS for Biological Big Data Sunwoo Lee Location: 442 Dana or Zoom Link Abstract: Minimally invasive and chronic physiological monitoring can provide an effective means of disease prevention and early detection while the cumulative big data can unveil hidden patterns in our physiology. Yet, current physiological monitoring tools are often bulky, invasive, and expensive, limiting their sensitivity and applicability. In this talk, I will discuss autonomous microsystems based on heterogeneously integrated CMOS,…

ECE Seminar: Emergent Active Photonic Platforms for Next-generation Mid-infrared and Ultrafast Photonics Qiushi Guo Location: 442 Dana or Zoom Link Abstract: As two basic properties of light, wavelength and timescale are central to numerous photonic applications. Compared to visible and near-infrared, the longer wavelength mid-infrared spectral regime contains unique thermal visual information and chemical fingerprints of the environment.  On a different front, femtosecond light sources and systems can enable ultrafast information processing, sensing, and computing. Yet, current chip-scale photonic devices…

ECE Seminar: Reinforcement Learning for Dynamical Systems with Temporal Logic Specifications Derya Aksaray Location: 442 Dana or Zoom Link Abstract: In many applications, dynamical systems such as drones, mobile robots, or autonomous cars need to achieve complex specifications on their trajectories which may include spatial (e.g., regions of interest), temporal (e.g., time bounds), and logical (e.g., priority, preconditions, concurrency among tasks) requirements. As these specifications become more complex, encoding them via algebraic equations become intractable. Alternatively, such specifications can be…

"Towards accurate and efficient edge computing via multi-task learning " Abstract: AI-powered applications increasingly adopt Deep Neural Networks (DNNs) for solving many prediction tasks, leading to more than one DNNs running on resource-constrained devices. Supporting many models simultaneously on a device is challenging due to the linearly increased computation, energy, and storage costs. An effective approach to address the problem is multi-task learning (MTL) where a set of tasks are learned jointly to allow some parameter sharing among tasks. MTL…
