    • ESE Fall Colloquium – “Using Information Geometry to Find Simple Models of Complex Processes”

    /
    Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    Effective theories play a fundamental role in how we reason about the world. Although real physical processes are very complicated, useful models abstract away the irrelevant degrees of freedom to give parsimonious representations. In contrast, overly complex models can be difficult to evaluate, suffer from numerical instabilities, and may overfit data. They also obscure useful […]

    ESE Ph.D. Thesis Defense – “Learning and Control of Network Phenomena”

    /
    Room 401B, 3401 Walnut 3401 Walnut Street, Philadelphia, PA, United States

    The intersection of dynamical systems and networks are used to model a huge variety of phenomena such as the spread of disease, multi-agent systems, opinions in social networks, and more. Many properties of these network phenomena can be understood by examining the eigenvalue spectrum of a matrix representation of the underlying graph. Using this intuition, […]

    CIS Seminar: “Generative multitask learning mitigates target-causing confounding”

    /
    Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

    We propose a simple and scalable approach to causal representation learning for multitask learning. Our approach requires minimal modification to existing ML systems, and improves robustness to prior probability shift. The improvement comes from mitigating unobserved confounders that cause the targets, but not the input. We refer to them as target-causing confounders. These confounders induce […]

    Fall 2022 GRASP SFI: Yasuo Kuniyoshi, University of Tokyo, “Behavior and Cognition Emerge and Develop From Embodiment – A Constructive Study of Human Fetus/Infant”

    /
    Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    This is a hybrid event with in-person attendance in Raisler Lounge (Towne 225) and virtual attendance via Zoom. This talk will NOT be recorded, please make sure to arrive on time. ABSTRACT In this talk, I will first show that physics of human-like body in action already provide certain information structure which can set the natural […]

    ASSET Seminar: Building Safe Autonomous Systems, Rahul Mangharam (University of Pennsylvania)

    /
    Levine 307 3330 Walnut Street, Philadelphia, PA, United States

    ABSTRACT: Balancing performance and safety are crucial to deploying autonomous vehicles in multi-agent environments. In particular, autonomous racing is a domain that penalizes safe but conservative policies, highlighting the need for robust, adaptive strategies. Current approaches either make simplifying assumptions about other agents or lack robust mechanisms for online adaptation. In this talk we will […]

    MSE Seminar: “Advanced Microscopy Techniques for Understanding Dislocation Interactions & Damage in Complex Microstructures”

    /
    Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

    Microstructurally and compositionally complex alloys (MCCA) such as Nickel-Aluminum-Bronze (NAB) are important to Navy and maritime applications due to their high strength, toughness, and fatigue resistance, as well as excellent corrosion resistance. NAB’s are widely used in many naval applications including ship propellers, underwater fasteners, pumps, and valves. Traditional sand cast NAB alloys tend to […]

    ESE Fall Colloquium – “Micro- and Nanoscale Electro-fluidics: From Basic Research to Translational Medicine”

    /
    Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    In this talk, I will discuss my group’s work on fabricating micro- and nanosensing platforms for health monitoring. My group has developed novel electronic sensing modalities and has demonstrated their use for both in vitro with human clinical samples and in vivo in animals. In the first part of my talk, I will discuss sensor […]

    ESE Ph.D. Thesis Defense – “Accelerating HLS Autotuning of Large, Highly-Parameterized Reconfigurable SoC Mappings”

    /
    Room 35, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

    High-level synthesis has accelerated the adoption of autotuners to explore design spaces. Design-space size increases exponentially in the number of design parameters, and synthesizing a single configuration for a device-scale application easily consumes hours, so existing autotuners are frequently demonstrated with small kernels and few configurations to render the problem tractable. This dissertation shows that […]

    BE Seminar: “Developments in Stem Cell-Derived Islets for Diabetes Cell Replacement Theory” (Jeffrey R. Millman, Washington University School of Medicine)

    /
    Glandt Forum, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

    This is a hybrid seminar which will be held in Glandt Forum (Singh Center) and via Zoom (link coming soon). "Developments in Stem Cell-Derived Islets for Diabetes Cell Replacement Theory" Cellular and tissue engineering promises new therapeutic options for people suffering from a wide range of diseases. Differentiation of stem cells is a powerful renewable […]

    A Celebration of the Life of Dr. Max Mintz

    /
    Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

    The CIS Department and GRASP Lab invite you to please join us on Thursday, November 17th, at 3:30pm as we celebrate the life and legacy of Dr. Max Mintz, Professor of Computer and Information Science. Max joined Penn as an assistant professor of Systems Engineering (now part of ESE) in 1974. He changed his primary […]

    ESE Ph.D. Thesis Defense – “Robustness of Temporal Logics with Applications to Safe Autonomy”

    /
    Zoom - Meeting ID 564 482 9525

    Signal Temporal Logic (STL) is a common way to express a broad range of real-time constraints that can be imposed on control systems. Spatial robustness of STL specifications, quantifying permissible spatial perturbations, has been widely studied in the literature. However, despite the importance of various time-critical systems, temporal robustness of STL has not yet been […]

    Fall 2022 GRASP on Robotics: Julie Adams, Oregon State University, “Towards Adaptive Human-Robot Teams: Workload Estimation”

    /
    Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

    This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance via Zoom.   ABSTRACT The ability for robots, be it a single robot, multiple robots or a robot swarm, to adapt to the humans with which they are teamed requires algorithms that allow robots to detect human performance in real time. The multi-dimensional […]
