  Talk Title
  Toward Faster Algebraic Computation: An Isomorphism Perspective

  Abstract

  "Over the past few decades, linear-algebraic techniques played a central role in the design of faster algorithms, with notable successes in many graph algorithms such as maximum flow and shortest paths. However, for many problems that are not yet known to admit polynomial-time algorithms—such as integer factoring and various isomorphism problems—linear methods alone are often insufficient. In these settings, more general nonlinear algebraic structures, including groups, rings, and modules, naturally arise. Achieving further algorithmic progress requires a deeper understanding of these algebraic objects.

  In this talk, I will discuss how algebraic representations have become essential to recent advances in isomorphism problems. I will highlight connections among several central isomorphism problems and survey the techniques that have led to more efficient algorithms. I will conclude by discussing open challenges and outlining promising directions for future research."

  CS Seminar: Data-Driven Neural Mesh Editing – without 3D Data (Rana Hanocka)

  Department of Computer Science (CS)

  12:00 PM 3514, Mudd Hall ( formerly Seeley G. Mudd Library)

  EVENT DETAILS

  Monday / CS Seminar
  March 2 / 12:00 PM
  Hybrid / Mudd 3514

  Speaker
  Rana Hanocka, University of Chicago

  Talk Title
  Data-Driven Neural Mesh Editing – without 3D Data

  Abstract
  Much of the current success of deep learning has been driven by massive amounts of curated data, whether annotated or unannotated. Compared to image datasets, developing large-scale 3D datasets is either prohibitively expensive or impractical. In this talk, I will present several works that harness the power of data-driven deep learning for tasks in shape editing and processing, without any 3D datasets. I will discuss works that learn to synthesize and analyze 3D geometry using large image datasets.

  Biography
  Rana Hanocka is an Assistant Professor at the University of Chicago and holds a courtesy appointment at the Toyota Technological Institute at Chicago (TTIC). She founded and directs the 3DL (Threedle) research collective, comprised of enthusiastic researchers passionate about 3D, machine learning, and visual computing. Her research interests span computer graphics, computer vision, and machine learning. She completed her Ph.D. at Tel Aviv University under the supervision of Daniel Cohen-Or and Raja Giryes. Her Ph.D. research focused on building neural networks for irregular 3D data and applying them to problems in geometry processing.
