    • PICS Colloquium: “Group-Theoretic Approach for Nonlinear Problems in Mechanics with High Symmetry Avoids Use of Imperfections”

    /
    PICS Conference Room 534 - A Wing , 5th Floor 3401 Walnut Street, Philadelphia, PA, United States

    Many interesting problems in nonlinear mechanics, from classical to more recent, pertain to applications with high initial symmetry: from the buckling of thin walled structures to the morphing in architected materials – the list is long! A common feature of these problems, in addition to their importance for engineering applications, is their great theoretical interest […]

    ESE Fall Colloquium – “On the Principles of Parsimony and Self-Consistency: Structured Compressive Closed-Loop Transcription”

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

    Ten years into the revival of deep networks and artificial intelligence, we propose a theoretical framework that sheds light on understanding deep networks within a bigger picture of intelligence in general. We introduce two fundamental principles, Parsimony and Self-consistency, that address two fundamental questions regarding Intelligence: what to learn and how to learn, respectively. We […]

    Tedori-Callinan Lecture: “Mixing of Granular Materials, Inertial Suspensions, and Cement”

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

    Flows of particulate materials are ubiquitous in nature and industry. Predictions of flow rates and mixing times rely on an understanding of the rheological properties of the materials, which can differ considerably from that associated with a single-phase fluid. This presentation highlights some unique features of granular materials and inertial suspensions and includes recent experimental […]

    ESE Ph.D. Thesis Defense: “Design of Low-power CMOS Integrated Systems: from Biomedical Applications to Optical Links”

    /
    Levine 512

    Electronic and photonic microsystems realized in the form of integrated circuits (IC) has been revolutionizing numerous fields that traditionally exploit bulky implementations. The advantages stemming from device miniaturization have opened up wide and growing opportunities to design for unprecedented functionality and enhanced performance. Leveraging novel CMOS and silicon photonic IC designs, this thesis presents four […]

    ASSET Seminar: Decision-Aware Learning for Global Health Supply Chains, Osbert Bastani (University of Pennsylvania)

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

    ABSTRACT: Machine learning algorithms are increasingly used in conjunction with optimization to guide decision making. A key challenge is aligning the machine learning loss with the decision-making loss. Existing solutions have limited flexibility and/or scale poorly to large datasets. We propose a principled decision-aware learning algorithm that uses a Taylor expansion of the optimal decision […]

    Fall 2022 GRASP SFI: Roberto Calandra, Meta AI, “Perceiving, Understanding, and Interacting through Touch”

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

    This is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom. ABSTRACT Touch is a crucial sensor modality in both humans and robots. Recent advances in tactile sensing hardware have resulted -- for the first time -- in the availability of mass-produced, high-resolution, inexpensive, and reliable tactile sensors. In this […]

    MSE Seminar: “Understanding Degradation in Metal Halide Perovskite Solar Cells and Modules”

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

    Halide perovskite solar cells (PSCs) have been the focus of much research in recent years due to their extremely high photoconversion efficiencies and their ability to be synthesized by solution processing.  These materials crystallize in the perovskite, AMX3 crystal structure where A is a monovalent cation (e.g. methyl ammonium, MA, formamidinium, FA, and/or Cs), M is the […]

    ESE Fall Colloquium – “Phase Transitions, Symmetry, and Reed-Muller Codes on BMS Channels”

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

    This talk will begin by discussing phase transitions in high-dimensional statistical inference problems. Some effort will be made to distinguish between problems with random structure (e.g., random codes and sparse PCA) and problems with deterministic structure (e.g., highly symmetric codes such as Reed-Muller codes). For problems with deterministic structure, we will observe that symmetry can […]

    ESE Ph.D. Thesis Defense: “Resilient, Information Theoretic, Active Exploration for Multi-Robot Teams”

    /
    Room 313, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

    Over the past decades we have seen robots move from constrained and heavily designed industrial environments out into the world. Along with this shift there is a need for smaller, safer, and less expensive robots which can complete tasks autonomously in teams, sometimes covering large areas. Multi-robot teams can expand the capabilities of a single […]

    Fall 2022 GRASP on Robotics: Radhika Nagpal, Princeton University, “Towards Collective Artificial Intelligence”

    /
    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 In nature, groups of thousands of individuals cooperate to create complex structure purely through local interactions — from cells that form complex organisms, to social insects like termites and ants that build nests and self-assemble bridges, to the […]
