Coupling from the Past 1

Aditya Suresh Gopalan (UIUC ISE )

Abstract: Abstract: The Coupling from the Past algorithm of Propp and Wilson is a good technique for sampling from and proving the existence of stationary distributions for Markov chains. In this talk, we discuss the proof of the technique. Briefly, the system works by constructing sequences sample paths whose initial states are determined by the previous element in the sequence, so that the original states are ``pushed to minus infinity'', thus establishing the coupling and convergence. This technique has applications to a wide variety of fields; one such application to interference queueing will be discussed in the next talk.

The Crochet Coral Reef: Intersections of Math, Science and Art through Hyperbolic Crochet

Margaret Wertheim, Artist

Abstract: Margaret Wertheim is a writer, artist and curator whose work intersects art, math and science as evidenced in her Crochet Coral Reef, an installation created through hyperbolic crochet. In this lecture Margaret will introduce the UIUC community to her work with the Institute for Figuring, a collaborative Los Angeles based practice started with Margaret's sister Christine in 2003. Devoted to the “aesthetic and poetic dimensions of science and mathematics,” the IFF has designed art & science exhibits for galleries and museums around the world. Margaret and Christine’s Crochet Coral Reef project is a global participatory art & science endeavor that has been seen by more than two million people and exhibited at the 2019 Venice Biennale. Margaret will discuss the interplay of art, science, and art as social practice in the Crochet Coral Reef project while promoting UIUC's very own locally made satellite reef, opening at the Siebel Center for Design September 23, 2021.
