    Theory Seminar- Aaron Roth (University of Pennsylvania)

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

    Abstract: Dawid gives two conceptualizations for models of individual probabilities: “Group to Individual” and “Individual to Group”. A classical concern about the “Group to Individual” view of probability is the reference class problem: Given that we can empirically measure only averages over many individuals, which group or “reference class” do we choose to average over […]

    MEAM Seminar: “Open Access Benchmark Datasets and Metamodels for Problems in Mechanics”

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

    Metamodels, or models of models, map defined model inputs to defined model outputs. When metamodels are constructed to be computationally cheap, they are an invaluable tool for applications ranging from topology optimization, to uncertainty quantification, to real-time prediction, to multi-scale simulation. In particular, for heterogeneous materials, metamodels are useful for exploring the influence of the […]

    ASSET Seminar: Explainable AI via Semantic Information Pursuit (René Vidal, Johns Hopkins University)

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

    Presentation Abstract: There is a significant interest in developing ML algorithms whose final predictions can be explained in domain-specific terms that are understandable to a human. Providing such an “explanation” can be crucial for the adoption of ML algorithms in risk-sensitive domains such as healthcare. This has motivated a number of approaches that seek to […]

    Fall 2022 GRASP SFI: Zhongyu Li, University of California Berkeley, “Can We Bridge Model-based Control and Model-free RL on Legged Robots?”

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

    *This will be a HYBRID Event with in-person attendance in Levine 307 and Virtual attendance via Zoom. In this talk, I will provide a brief introduction about our recent progress in applying optimal control and deep reinforcement learning (RL) on legged robots in the real world. I will then dive into our recent work to […]

    MSE Seminar: “Materials Growth and Discovery for Magnetic and Quantum Applications”

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

    For functional materials that are in a nascent stage, such as the antiferromagnetic spintronics, quantum information storage, and new semiconducting compounds, it is not clear what will be the high-performance materials of tomorrow. There is a pressing need to examine the complex properties of these emerging materials, and growing single crystals is a crucial step […]

    Theory Seminar- Recent Developments in Combinatorial Auctions, Matt Weinberg (Princeton University)

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

    Abstract: In a combinatorial auction there are m items, and each of n players has a valuation function v_i which maps sets of items to non-negative reals. A designer wishes to partition the items into S_1,…,S_n to maximize the welfare (\sum_i v_i(S_i) ), perhaps assuming that all v_i lie in some class V (such as […]

    MEAM Seminar: “Manually-Operated, Slider Cassette for Multiplexed Molecular Detection at the Point of Care”

    /
    Room 2C8, David Rittenhouse Laboratory Building 209 South 33rd Street, Philadelphia, PA, United States

    Effective control of epidemics, individualized medicine, and new drugs with virologic response-dependent dose and timing require, among other things, simple, inexpensive, multiplexed molecular detection platforms suitable for point of care and for home use. Conventional molecular detection methods such as PCR tests, require bulky and expensive equipment, trained personnel, and specialized laboratories, limiting their use […]
