  Victor Barranca: Reconstruction of Neuronal Network Connectivity and Rivalrous Percepts Via Compressive Sensing of Network Dynamics

  McCormick-Engineering Sciences and Applied Mathematics (ESAM)

  11:15 AM M416 and online at https://northwestern.zoom.us/j/96091762215, Technological Institute

  EVENT DETAILS

  Title: Reconstruction of Neuronal Network Connectivity and Rivalrous Percepts Via Compressive Sensing of Network Dynamics

  Speaker: Victor Barranca, Associate Professor of Mathematics, Swarthmore College

  Abstract: Neuronal network connectivity demonstrates sparsity on multiple spatial scales and natural stimuli also possess sparse representations in numerous domains. In this talk, we underline the role of sparsity in the efficient encoding of network connectivity and inputs through nonlinear neuronal network dynamics. Addressing the fundamental challenge of recovering the structural connectivity of large-scale neuronal networks, we leverage properties of the balanced dynamical regime and compressive sensing theory to develop a theoretical framework for efficiently reconstructing sparse network connections through measurements of the network response to a relatively small ensemble of random stimuli. We further utilize sparse recovery ideas to probe the neural correlates of binocular rivalry through dynamic percept reconstructions based on the activity of a two-layer network model with competing downstream pools driven by disparate image stimuli. The resultant model dynamics agree with key experimental observations and give insights into the excitation/inhibition hypothesis for autism.

  Professional Development Series: Team Dynamics/Leading and Working on Effective Teams

  McCormick School of Engineering and Applied Science

  12:00 PM 101 Wildcat Room, Norris University Center

  EVENT DETAILS

  

  Join us for a series of professional development events hosted by McCormick HR. The first fall event of the series will focus on team dynamics.

  This session is an interactive program covering a framework of best practices and skills in building and leading a team that performs with excellence. The objective of this session is to provide tools that will enhance communication between team members, clearer understanding of what's expected, and increased accountability for both the leader and the team member.

  This event is voluntary and open to all Northwestern Engineering staff, faculty, postdocs, and research staff.

  If you have questions or accessibility needs, please contact Kimberly Higgins.

  Training provided by Cindy Aaronson, Organizational Consultant and Trainer with CSA & Associates.

  Michael Graham: Data, Dynamics, and Manifolds: Machine Learning Approaches for Modeling and Controlling Complex Flows

  McCormick-Engineering Sciences and Applied Mathematics (ESAM)

  4:00 PM M113, Technological Institute

  EVENT DETAILS

  Title: Data, Dynamics, and Manifolds: Machine Learning Approaches for Modeling and Controlling Complex Flows

  Speaker: Michael Graham, Cheimcal & Biological and Mechanical Engineering , University of Wisconsin-Madison

  Abstract: This lecture will outline how exploitation of symmetries substantially improves performance in accurately simulating chaotic or turbulent fluid flows. Graham will describe a data-driven reduced order modeling method, “Data-driven Manifold Dynamics,” that finds a nonlinear coordinate representation of the manifold using a machine-learning architecture called an autoencoder, then learns an ordinary differential equation for the dynamics on the manifold.

  **Please note, this event will be held in-person, as well as online via Zoom. Register for attendance or for the webinar at the following link: https://www.mccormick.northwestern.edu/applied-math/news-events/stephen-davis-symposium/
