    • ASSET Seminar: Using Large Language Models to Build Explainable Classifiers, Chris Callison-Burch (University of Pennsylvania)

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

    ABSTRACT: I'll present research on using large language models (LLMs) to build explainable classifiers.   I will show off work from my PhD students and collaborators on several recent research directions: Image classification with explainable features  (https://arxiv.org/abs/2211.11158) Text classification with explainable features (work in progress) The importance of faithfulness in explanations (https://arxiv.org/abs/2209.11326) (Time permitting) A […]

    Spring 2023 GRASP SFI: Melkior Ornik, University of Illinois Urbana-Champaign, “System Resilience and Guaranteed Performance in the Face of Unexpected Adversity”

    /
    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. This week's presenter will be in-person as well. ABSTRACT The ability of a system to correctly respond to a sudden adverse event is critical for high-level autonomy in complex, changing, or remote environments. By assuming continuing structural knowledge about […]

    ESE Spring Seminar – “Reliable Data-Driven Decision-Making Systems”

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

    Despite impressive success in domains such as vision and language, machine learning is still far from reliable integration into many challenging real-world scenarios, such as healthcare, where the coverage of existing data and the ability to collect new, diverse data are limited. This talk focuses on mathematically formulating and addressing some of the challenges in […]

    BE Seminar: “Probing Metabolism Across Scales” (Yihui Shen, Princeton University)

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

    Metabolism supports the biosynthetic and energetic demand of all living creatures. Over decades, we have accumulated knowledge of how individual enzymes work in vitro, but we don’t have a good sense about how they work together in vivo. Thus, fundamental to our understanding of metabolic operation is the ability to measure metabolic activity in vivo. […]

    CIS Seminar: “Software Security Challenges in the Era of Modern Hardware”

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

    Today’s hardware cannot keep secrets. Indeed, the past two decades have seen the discovery of a slew of attacks where an adversary exploits hardware features to leak software’s sensitive data. These attacks have shaken the foundations of computer security and caused a major disruption in the software industry. Fortunately, there has been a saving grace, namely the widespread adoption […]

    Spring 2023 GRASP on Robotics: Rodney Brooks, Robust.AI, “Academic research: exploration vs exploitation”

    /
    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. This week's presenter will be in-person as well.    ABSTRACT Intelligent action is critical in robotics, more so than much of AI where results are often mediated by humans in the loop. That said, robotics also needs to […]

    PICS Colloquium: “Building and using virtual models of the tricuspid valve toward better understanding, diagnosis, and treatment of its diseases”

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

    Computer simulations have become critical elements of the medical device design and regulatory approval process. Naturally, the predictability and therefore value of such simulations depends highly on their accuracy. Especially for the design of heart valve replacements and repair technologies computer simulations have become a critical tool. While much progress has been made in modeling […]

    MEAM Seminar: “Data-Aware Computational Models for Science and Engineering”

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

    In the past half-century, partial differential equation (PDE)-based computational models have emerged as indispensable for science and engineering. However, remarkable gaps still exist between state-of-the-art simulations and reality, meaning that many simulations are ineffective in supporting decision-making or design under uncertainty for complex systems (e.g., Mars landing). To bridge the gap and fulfill challenging real-world […]

    CIS Seminar: “Rethinking System Design for Expressive Cryptography”

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

    Expressive cryptography, including Secure Multi-Party Computation (SMPC) and Fully Homomorphic Encryption (FHE), has the potential to enable transformative new applications, drawing significant interest from industry. Unfortunately, it is often slow and resource-intensive, making those applications difficult to realize. For example, SMPC enables multiple organizations (e.g., hospitals) to run joint computations on their data (e.g., for […]

    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 […]

    CIS Seminar: “Methods of Data Lookup with Hashing”

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

    We will discuss methods of data lookup, with a focus on hash sets / tables, including motivation, properties, and variants. This will be in the context of a "CS 2" or data structures course. We will assume a basic familiarity with programming and comfort with implementing resizable lists; as well as knowledge of (but not […]
