  Appl Math: Mariela Petkova on "Carving Circuits from Correlative Connectomics"

  McCormick-Engineering Sciences and Applied Mathematics (ESAM)

  11:15 AM M416, Technological Institute

  EVENT DETAILS

  Title: Carving Circuits from Correlative Connectomics

  Speaker: Mariela Petkova, Harvard University

  Abstract: Tracing the wiring diagram of a neural circuit is a powerful approach to test
  computational models of brain function. Connectomics – the mapping of
  neurons and their connections in the brain – poses formidable technical and
  conceptual challenges. The former entails the acquisition and reduction of
  vast amounts of electron microscopy image data to connectivity matrices,
  achieved through multi-year, multi-team collaborative efforts. The latter
  challenge is the problem of coarse-graining the connectivity matrices to
  neural circuits which exhibit neural activity and function. I will describe both
  challenges in the context of mapping the nervous system of a small
  vertebrate – the larval zebrafish. In the same animal, we pair electron
  microscopy with functional information from light microscopy to interrogate
  neural circuit models for animal behavior from sensory inputs to motor output.

  Appl Math: Yiping Lu on "Two Tales, One Resolution: Physics-Informed Test Time Scaling and Precondition"

  McCormick-Engineering Sciences and Applied Mathematics (ESAM)

  11:15 AM M416, Technological Institute

  EVENT DETAILS

  Title: Two Tales, One Resolution: Physics-Informed Test Time Scaling and Precondition

  Speaker: Yiping Lu, Northwestern University

  Abstract: In this talk, I will introduce a novel framework for physics-informed debiasing of machine learning estimators, which we call Simulation-Calibrated Scientific Machine Learning (SCaSML). This approach leverages the structure of physical models to achieve two key objectives:

  Unbiased Predictions: It produces unbiased predictions even when the underlying machine learning predictor is biased.
  Overcoming Dimensionality Challenges: It mitigates the curse of dimensionality that often affects high-dimensional estimators.

  The SCaSML paradigm integrates a (potentially) biased machine learning algorithm with a de-biasing procedure that is rigorously designed using numerical analysis and stochastic simulation. Our methodology aligns with recent advances in inference-time computation—similar to those seen in the large language model literature—demonstrating that additional computation can enhance ML estimates. Furthermore, we establish a surprising equivalence between our framework and another research direction that utilizes approximate (linearized) solvers to precondition iterative methods. This connection not only bridges two distinct areas of study but also offers new insights into improving estimation accuracy in complex, high-dimensional (PDE) settings.
