Stats, Optimization, and Machine Learning Seminar - Amir Ajalloeian, Maddela Avinash, Ayoub Ghriss

Dec. 10, 2019

Amir Ajalloeian; Department of Electrical, Computer, and Energy Engineering; University of Colorado Boulder Inexact Online Proximal-gradient Method for Time-varying Convex Optimization This paper considers an online proximal-gradient method to track the minimizers of a composite convex function that may continuously evolve over time. The online proximal-gradient method is "inexact,'' in...

Math Bio Seminar - Dan Messenger

Dec. 10, 2019

Dan Messenger, Department of Applied Mathematics, University of Colorado Boulder Aggregation-Diffusion Phenomena in Domains with Boundaries This talk relates to a class of mathematical models for the collective behaviour of autonomous agents, or particles, in general spatial domains, where particles exhibit pair-wise interactions and may be subject to environmental forces...

Applied Math Colloquium - Leonid Berlyand

Dec. 6, 2019

Leonid Berlyand, Department of Mathematics, Penn State University PDE models of Active Matter In this talk we attempt to demonstrate how mathematical analysis could be helpful in the study of active matter, with the focus on active gels and cell motility. We first discuss mathematical challenges and developments of novel...

Stats, Optimization, and Machine Learning Seminar - Sriram Sankaranarayanan

Nov. 12, 2019

Sriram Sankaranarayanan, Department of Computer Science, University of Colorado Boulder Reasoning about Neural Feedback Systems Data-driven components such as feedforward neural networks are increasingly being used in critical safety systems such as autonomous vehicles and closed-loop medical devices. Neural networks compute nonlinear functions. Relatively tiny networks present enormous challenges for...

Math Bio Seminar - Jimmy Garnier

Nov. 12, 2019

Jimmy Garnier, Laboratoire de mathématiques, Université de Savoie Genetic and demographic consequences of fast propagation Dispersal is one of the critical processes during the spreading stage of biological invasions. In particular, long-distance dispersal events may increase the dispersibility of invasive species and thus accelerate the spread of the biological invasion...

Applied Math Colloquium - Katherine Morrison

Nov. 8, 2019

Katherine Morrison, School of Mathematical Sciences, University of Northern Colorado Predicting neural network dynamics from graph structure Neural networks often exhibit complex patterns of activity that are shaped by the intrinsic structure of the network. For example, spontaneous sequences of neural activity have been observed in cortex and hippocampus, and...
