    • CIS Seminar: ” Specializing LLMs for Reliability”

    /
    Amy Gutmann Hall, Room 414 3333 Chestnut Street, Philadelphia, United States

    Large language models (LLMs) have advanced the frontiers of AI reasoning: they can synthesize information from multiple sources, derive new conclusions, and explain those conclusions to their users. However, LLMs do not do this reliably. They hallucinate facts, convincingly state incorrect deductions, and exhibit logical fallacies like confirmation bias. In this talk, I will describe […]

    Spring 2025 GRASP SFI: Harshil Parekh, BotBuilt, “From GRASP to BotBuilt: Using Robotics and AI to Revolutionize Construction”

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

    This will be a hybrid event with in-person attendance in Levine 307 and virtual attendance on Zoom. ABSTRACT Construction remains one of the least automated industries, struggling with labor shortages, inefficiencies, and rising costs. At BotBuilt, we are revolutionizing the way homes are built by leveraging robotics and AI to automate framing, making construction faster, […]

    CBE Seminar: “Prioritization of Research, Development, and Deployment Pathways for a Circular Bioeconomy” (Jeremy Guest, UIUC)

    /
    Wu & Chen Auditorium

    Abstract: Societies have prospered using a linear “take-make-use-dispose” approach, extracting natural resources to make products, using them, and ultimately discarding them or their residues. This unsustainable approach has exploited natural resources at a rate that has caused excessive pollution and loss of biodiversity, and is leading to a global climate crisis. In response to this […]

    CBE Seminar: “Machine-learning-assisted Atomistic Modeling and Design of Complex Ionic Conductors for Next-Generation Energy Storage” (KyuJung Jun, MIT)

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

    Abstract: Fast solid-state Li-ion conductors are a crucial class of materials with the potential to enable all-solid-state batteries, offering enhanced safety and energy density. However, these materials remain rare, and progress in developing novel solid electrolytes has been hindered by a lack of clear descriptors for superionic conductivity and a limited understanding of ion transport […]

    IDEAS/STAT Optimization Seminar: “ML for an Interactive World: From Learning to Unlearning”

    /
    Amy Gutmann Hall, Room 414 3333 Chestnut Street, Philadelphia, United States

    The remarkable recent success of Machine Learning (ML) is driven by our ability to develop and deploy interactive models that can solve complicated tasks by understanding and adapting to the ever-changing state of the world. However, the development of such models demands significant data and computing resources. Moreover, as these models increasingly interact with humans, […]

    BE Seminar – “Scaffold-Modulated Healing in Irradiated Bone” (Katie Hixon, Dartmouth Engineering)

    /
    Berger Auditorium (Room 13), Skirkanich Hall 210 South 33rd Street, Philadelphia, PA, United States

    Bone is the third most common site for cancer metastasis, affecting ~66% of patients with common cancers—breast, lung, prostate, renal, thyroid—incurring skeletal events in up to 400,000 people in the US/year. Metastatic bone disease (MBD) results in weakened bone, leading to refractory pain and pathological fracture that increase disease state morbidity. Despite bone tissue’s dynamic […]

    CIS Seminar: “Realizing the Promise of Language-level Security in Real Systems”

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

    Promises are cheap. Software vendors routinely describe their offerings as “secure”, but few are based on designs that can guarantee even the most basic security properties. To address this problem, services like Cloudflare, Android, and Firefox are increasingly relying on languages like Rust and WebAssembly to provide safety by design. But these promises too can […]

    CIS Seminar: “Privacy, Copyright, and Data Integrity: The Cascading Implications of Generative AI”

    /
    Amy Gutmann Hall, Room 414 3333 Chestnut Street, Philadelphia, United States

    The rapid adoption of generative AI has created a cycle where personal information cascades perpetually: from people to models to applications and online platforms, then back through scrapers into the system. Simple blanket rules such as "don't train on this data" or "don't share sensitive information" are inadequate, as we face training data scarcity while […]

    Spring 2025 GRASP on Robotics: Bruno Olshausen, University of California, Berkeley & Redwood Center for Theoretical Neuroscience, “Invariance and equivariance in brains and machine”

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

    This will be a hybrid event with in-person attendance in Wu and Chen and virtual attendance on Zoom. ABSTRACT The goal of building machines that can perceive and act in the world as humans and other animals do has been a focus of AI research efforts for over half a century. Over this same period, […]

    CIS Seminar: “Intelligence Augmentation for Scientific Researchers”

    /

    Special location for this talk: 105  Amy Gutmann Hall Recent advances in Artificial Intelligence are powering revolutionary interactive tools that will transform the very nature of the scientific enterprise. We describe several large-scale projects at the Allen Institute for AI aimed at developing open models, agentic platforms, and novel interaction paradigms in order to amplify […]

    MSE Thesis Defense: “Chain and Pendant Architecture Effects in Associating Polyolefins” Eli Jared Fastow

    /
    Wu & Chen Auditorium

    The United States recycles less than 9% of plastic waste, representing a tremendous environmental catastrophe and a loss of embodied value. This dissertation presents the structure-property relationships of functional polymers made from an upcycling approach targeting polyolefins for polymer-to-polymer conversions. The overall strategy proceeds by first dehydrogenating polyolefins, then functionalizing the resulting C=C to generate […]

    Spring 2025 GRASP Seminar: James Tompkin, Brown University, “Joint Depth and 3D Motion Estimation Two Ways”

    /
    Levine 512

    This will be a hybrid event with in-person attendance in Levine 512 and virtual attendance on Zoom. This seminar will NOT be recorded. ABSTRACT Dynamic scene reconstruction from monocular cameras often requires us to simultaneously estimate depth and 3D motion, where knowledge of either one would help to constrain the other. I will review two […]
