SUMMARY:Daniel Forger: The mathematics of the wearable revolution, with applications to circadian rhythms and COVID detection
LOCATION:
DESCRIPTION:Title: The mathematics of the wearable revolution, with applications to circadian rhythms and COVID detection\nSpeaker: Daniel Forger, PhD, University of Michigan\nSpecial Note: This colloquium will be held at https://northwestern.zoom.us/j/93379493447. The passcode is 685321. \nAbstract:\nMillions of Americans track their steps, heart rate, and other physiological signals through wearables. This data scale is unprecedented. I will describe several of our apps and ongoing studies, each of which collects wearable and mobile data from thousands of users, even in > 100 countries. This data is so noisy that it often seems unusable in desperate need of new mathematical techniques to extract key signals used in the (ode) mathematical modeling typically done in mathematical biology. I will describe several techniques we have developed to analyze this data and simulate models, including gap orthogonalized least squares, a new ansatz for coupled oscillators, which is similar to the popular ansatz by Ott and Antonsen, but which gives better fits to biological data and a new level-set Kalman Filter that can be used to simulate population densities. My focus application will be determining the phase of circadian rhythms in the real world and the detection of COVID with wearables.\n------\nTo subscribe to the Applied Mathematics Colloquia List send the message\n"subscribe esam-seminar " to listserv@listserv.it.northwestern.edu\n\nPiP URL: https://planitpurple.northwestern.edu/event/570758
