    CIS Seminar: “Pareto-efficient AI systems: Expanding the quality and efficiency frontier of AI”

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

    We have made exciting progress in AI by massive models on massive amounts of data center compute. However, the demands for AI are rapidly expanding. I identify how to maximize performance under any compute constraint, expanding the Pareto frontier of AI capabilities.   This talk builds up to an efficient language model architecture that expands […]

    Spring 2025 GRASP on Robotics: Reid Simmons, Carnegie Mellon University, “AI-Based Assistants for the Elderly”

    /
    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 As the population ages, the need grows for AI agents to assist people to remain living independently.  Older adults are typically set in their ways, so AI agents should adapt to their ways of doing things, […]

    Women in Data Science @ Penn Conference: From Data to Discovery: Exploring AI with a Patient Case Study, ChatGPT and Generative Models

    /
    Jon M. Huntsman Hall 3730 Walnut Street, Philadelphia, PA, United States

    In today’s data-driven landscape, vast unstructured data sources — like documents and electronic health records (EHRs) — demand advanced AI tools to unlock their full potential. Generative AI, powered by large language models (LLMs), is becoming indispensable for processing and extracting insights from complex language-based data. Participants will explore: Identifying key problems that lend themselves to AI-driven solutions. Collecting and preparing data, building models and running state-of-the-art algorithms. […]

    CBE Doctoral Dissertation Defense: “Understanding and Modulating Interactions between Polymers and Nanoparticles for Effective Catalyst Design in Polymer Upcycling” (Anirban Majumder)

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

    Abstract: Despite recent advances in catalytic conversion of plastic waste into high-value chemicals, the interactions between the polymers and catalysts, which are highly porous nanomaterials, are not well understood. Fundamental understanding of these interactions and the ability to modulate them would allow us to design effective catalysts for polymer upcycling reactions. To study the interactions […]

    MEAM Seminar: “Learning Memory and Material Dependent Constitutive Laws”

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

    The theory of homogenization provides a systematic approach to the derivation of macroscale constitutive laws, obviating the need to repeatedly resolve complex microstructure. However, the unit cell problem which defines the constitutive model is typically not amenable to analytical solution. It is therefore of interest to learn constitutive models from data generated by the unit […]

    ASSET Seminar: “Alignment and Control with Representation Engineering”

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

    Abstract: Large Language Models (LLMs) are vulnerable to adversarial attacks, which bypass common safeguards put in place to prevent these models from generating harmful output. Notably, these attacks can be transferrable to other models---even proprietary ones—potentially compromising a wide range of AI systems with a single exploit. This surprising fragility underscores a critical weakness in […]

    Spring 2025 GRASP SFI: Lillian Ratliff, University of Washington, “Fragile Foundations? Building Robustness into Reasoning with Algorithmic Agents”

    /
    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 As AI-enabled systems become integral to critical domains, their robustness is increasingly tested by dynamic environments, continual learning, and inferential uncertainty. Whether an AI proxy informs high-stakes medical decisions or an embodied agent relies on a foundation […]

    CBE Seminar: “Value-added Transformations in Electrocatalysis and Graduate Education” (Maureen Tang, Drexel University)

    /
    Wu & Chen Auditorium

    Abstract: Electrifying the chemical industry has been much touted as a path to a low-carbon future, but nearly all pathways of interest are electrochemical reductions. If we want water-to-hydrogen, CO2-to-chemicals, or nitrogen-to-ammonia, from where will we get the electrons? Water-to-oxygen is thermodynamically expensive, kinetically slow, and generates a zero-value product. This talk will discuss two […]

    MEAM Ph.D. Thesis Defense: “Macroscopic Ensemble Methods for Multi Robot Task Assignment in Dynamic Environments”

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

    With finite resources to complete tasks like monitoring, coverage, and search, the challenge lies in identifying and performing tasks that can change both in frequency and location. One potential solution is teams of robots equipped with the necessary capabilities to complete the desired tasks. However, robot teams require methods that effectively assign robots to tasks, […]

    MSE/MEAM Seminar: “Converting Scientific Discovery and Disruptive Ideas Into Impactful Energy Technologies with ARPA-E” Laurent Pilon: ARPA-E

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

    This talk presents the Advanced Research Projects Agency-Energy (ARPA-E) and how stakeholders at the University of Pennsylvania can engage in a dialog with the funding agency. ARPA-E advances high-risk high-impact transformational technologies to generate, store, and use energy. As part of the US Department of Energy, ARPA-E’s mission is to enhance the economic and energy […]

    IDEAS/STAT Optimization Seminar: “Gradient Equilibrium in Online Learning”

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

    We present a new perspective on online learning that we refer to as gradient equilibrium: a sequence of iterates achieves gradient equilibrium if the average of gradients of losses along the sequence converges to zero. In general, this condition is not implied by, nor implies, sublinear regret. It turns out that gradient equilibrium is achievable […]
