  • CS Colloquium: Aditya Grover (Stanford University) - Mitigating Bias in Generative Modeling

    Tue, Oct 29, 2019 @ 02:00 PM - 03:00 PM

    Thomas Lord Department of Computer Science

    Conferences, Lectures, & Seminars

    Speaker: Aditya Grover, Stanford University

    Talk Title: Mitigating Bias in Generative Modeling

    Series: Computer Science Colloquium

    Abstract: In the last few years, there has been remarkable progress in deep generative modeling. However, the learned models are noticeably inaccurate w.r.t. to the underlying data distribution, as evident from downstream metrics that compare statistics of interest across the true and generated data samples. This bias in downstream evaluation can be attributed to imperfections in learning ("model bias") or be propagated due to the bias in the training dataset itself ("dataset bias"). In this talk, I will present an importance weighting approach for mitigating both these kinds of biases of generative models. Our approach assumes only 'black-box' sample access to a generative model and is broadly applicable to both likelihood-based and likelihood-free generative models. Empirically, we find that our technique consistently improves standard goodness-of-fit metrics for evaluating the sample quality of state-of-the-art deep generative models, suggesting reduced bias. We demonstrate its utility on representative applications in a) data augmentation and b) model-based policy evaluation using off-policy data. Finally, I will present some recent work extending these ideas to fair data generation in the presence of biased training datasets.

    This lecture satisfies requirements for CSCI 591: Research Colloquium.

    Biography: Aditya Grover is a 5th-year Ph.D. candidate in Computer Science at Stanford University advised by Stefano Ermon. His research focuses on probabilistic machine learning, including topics in generative modeling, approximate inference, and deep learning as well as applications in sustainability. His research has been cited widely in academia, deployed into production at major technology companies, and recognized with a best paper award (StarAI), a Lieberman Fellowship, a Data Science Institute Scholarship, and a Microsoft Research Ph.D. Fellowship. He is also a Teaching Fellow at Stanford since 2018, where he co-designed and teaches a new class on Deep Generative Models. Previously, Aditya obtained his bachelors in Computer Science and Engineering from IIT Delhi in 2015, where he received a best undergraduate thesis award.

    Talk Title: Thermal-emission engineering: challenges and opportunities

    Abstract: Thermal emission (thermal radiation) is the phenomenon responsible for most of the light in the universe. Though understanding of thermal emission dates back over a century, recent advances have encouraged the re-examination of this phenomenon and its applications. This talk will describe our groups advances and outline future work in the measurement and manipulation of thermal emission. First, I will discuss our efforts to improve thermal-emission metrology, especially for low-temperature thermal emitters, emitters with temperature-dependent emissivity, and emitters out of equilibrium. Then, I will describe our use of phase-transition materials including vanadium dioxide and rare-earth nickelates to demonstrate new phenomena, including negative- and zero-differential thermal emittance, radiative thermal runaway, and thermo-dichroism. I will also discuss our recent demonstration of nanosecond-scale modulation of emissivity and thermal-emission pulses down to picosecond scales. The talk will include discussion of exciting opportunities of thermal-emission engineering for infrared camouflage and thermoregulation.
