Estimating Eigenvalues Using the Lanczos Method

Meeting ID: 956 2126 9525 Passcode: 353328 Zoom Meeting
  • John Urschel, Ph.D. Candidate, Department of Mathematics, Massachusetts Institute of Technology
Estimating the eigenvalues of a matrix is a fundamental problem in numerical linear algebra. The Lanczos method is a Krylov subspace technique for Hermitian matrices. In this talk, we will briefly introduce the Lanczos method, review classical results, and examine both new error estimates for this algorithm and ways in which the Lanczos method can be used to obtain improved...

High Dimensional Expanders and analysis of Markov Chains

Zoom link: Evans Hall
  • Shayan Oveis Gharan, University of Washington
Most interesting probability distributions that appear in science and mathematics have exponentially large support and we are unable to study them precisely. Researchers, typically, simulate Markov chains and hope that after running the chain long enough it generates random samples from the target distribution. Samples can then be exploited to estimate several quantities of interests such as...

Dissertation Talk: Mobile Robot Learning

  • Gregory Kahn
In order to create mobile robots that can autonomously navigate real-world environments, we need generalizable perception and control systems that can reason about the outcomes of navigational decisions. Learning-based methods, in which the robot learns to navigate by observing the outcomes of navigational decisions in the real world, offer considerable promise for obtaining these intelligent...

CCB Seminar: Regulation of stem cell homeostasis - The role of a ribosomal RNA intron

Zoom Seminar
  • Dr. Eliezer Calo, Department of Biology, MIT
Abstract: Here, I present work on genomic epidemiology of Ebola virus and evolutionary dynamics of seasonal influenza virus. In both cases, we're using the Nextstrain platform to pull in sequence data in near real-time and generate inferences of epidemic patterns. For the ongoing outbreak of Ebola in North Kivu in the DRC, inferences focus on individual-level transmission patterns to aid in...
