11:00 AM - 7:00 PM

Home: American photography at the CU Art Museum
March 2 - July 15, 2017

Is home “where the heart is”? Is it a building, a landscape or a state of mind? Drawn from the photography collection of the CU Art Museum, Home investigates how American photographers working from the late 1800s to today have engaged with these questions. Through a presentation of landscapes, family photos and candid portraits visitors are invited to consider central themes of the exhibition, including environment, nostalgia and family.

What does home mean to you?
We invite our guests to respond to the images and ideas presented in the exhibition by visiting a special programming space in our FlexSpace gallery, open from February 2, 2017–March 25, 2017.

This exhibition is generously supported by CU-Boulder Student Arts and Cultural Enrichment fees, and CU Art Museum members.

Stopping games

We consider a stopping game in which the game ends after all the players' stopping. Instead of being the usual stopping times, the stopping strategies used by the players can be adjusted according to other players' behaviors. We first consider the zero-sum games both in discrete and continuous time. We convert the original game into a Dynkin game, and show that the value of the original game exists in some sense and is equal to the value of the Dynkin game. Then we consider the non-zero-sum case. We show that under some assumptions there always exists an epsilon Nash equilibrium.

Bistability and Hopf Bifurcation in a Refined Model of the Acute Stage of HIV Infection

Recent clinical studies have shown that HIV disease pathogenesis can depend strongly on many factors at the time of transmission, including the strength of the initial viral load and the local availability of CD4+ T-cells. To facilitate these new advances, we will describe a refined in-host model of HIV infection that incorporates the homeostatic proliferation of T-cells. Due to the effects of this biological process, the influence of initial conditions on the proliferation of HIV infection and the dynamics of the model is further elucidated.  In particular, our study of the new model extends previous theoretical and computational work on the acute stage of the disease and leads to interesting nonlinear dynamics, including a parameter region featuring bistability of infectious and viral clearance equilibria and the appearance of a Hopf bifurcation within biologically relevant parameter regimes, which may be linked to the appearance of so-called “viral blips”

Blended Bayesian Intelligence for Collaborative Autonomous Systems (Big and Small) 

ABSTRACT: The age of autonomy has arrived. However, as autonomous systems are products of imperfect human engineering designed to make decisions in an uncertain world, the promise of ‘set-it-and-forget-it’ autonomy is still quite far off: autonomous systems will never operate out of the box “exactly right.” For sufficiently rich tasks that constantly push the technological cutting edge, they will encounter unexpected situations that require reasoning beyond their designed/immediate capabilities. As such, intelligent autonomy must not only be able to independently gather, process and act on information – it should also be cognizant of what it can and cannot accomplish, and know when and how to seek help.

Human-machine and machine-machine interaction are thus key components of autonomous system design, and these must naturally integrate with existing perception, planning, learning and reasoning algorithms for single agent autonomy. An autonomous robot, for instance, should ideally enable human stakeholders and users to fluidly (re-)delegate tasks to the system, assess information, and contribute  meaningful operational improvements -- without requiring users to “babysit,” act as a “Band-Aid” when all else fails, or think too hard about what the system is trying to do. When combined into large scale networked teams, intelligent autonomous robots should also be able to efficiently exchange and extract relevant information from one another to improve both local and global reasoning under uncertainty – even if they have heterogeneous/asymmetrical capabilities and tasks to complete. 

In this talk, Ahmed will discuss novel Bayesian approaches to collaborative human-robot and robot-robot reasoning that can be exploited from the outset in autonomous system design. The first part of the talk will focus on probabilistic modeling and inference techniques for augmenting autonomous sensing and state estimation algorithms with plug-in “human sensor” inputs, provided via user-friendly semantic interfaces (e.g. natural language, sketching). The second part of the talk will highlight the important issue of scaling autonomous Bayesian reasoning to large distributed networks. In particular, Ahmed will show how factorized decentralized data fusion (FDDF) methods can be used to create a “GitHub for uncertainty” that allows agents to efficiently exchange conditional chunks of statistical information on demand across disparate local world models. Results from collaborative human-robot target search and multi-platform target tracking applications show that these techniques allow autonomous teams to gracefully “fill in the gaps and cut the knots” for challenging uncertain reasoning problems – without undermining individual agent roles or ignoring the limitations of individual autonomous agents.

Title: “Probing the Warped Side of the Universe with Gravitational Waves: From the Big Bang to Black Holes”

Presented by: Dr. Kip S. Thorne

Doors open at 7, lecture begins at 7:30

Abstract: Gravitational waves are ripples in the fabric of space and time predicted by Albert Einstein 100 years ago. After a half century effort, we humans have had our first contact with these waves. LIGO (the Laser Interferometer Gravitational-wave Observatory) has detected and deciphered gravitational waves produced by pairs of colliding black holes a billion light years from Earth. Thorne will describe LIGO and its discoveries, and the future of gravitational-wave astronomy: A future that will include at least four different frequency bands (the gravitational analogs of X-ray, optical, infrared, and radio astronomy); and a future in which astronomers will probe a rich range of phenomena, including the birth of the universe and the birth of the fundamental forces of nature in our universe’s earliest moments.

Kip Thorne is the Richard P. Feynman Professor of Theoretical Physics, Emeritus, at the California Institute of Technology in Pasadena, California. He is a theoretical physicist specializing in the astrophysical effects of Einstein’s General Theory of Relativity, especially black holes and gravitational waves. He was one of the founding members of the Laser Interferometer Gravitational Wave Observatory (LIGO) in 1984. The goal of LIGO is to observe gravitational waves from extreme astrophysical events. Gravitational waves were first predicted by Albert Einstein one-hundred years ago this year. While there is good indirect evidence for gravitational waves based on the behavior of binary pulsars, the first direct measurement of a gravitational wave was announced by the LIGO team on February 11, 2016. Two independent laser interferometers in Livingston, Louisiana and Hanford, Washington observed a gravitational wave on September 14, 2015. Analysis of the signal indicates the wave was produced by the collision of two black holes more than one-billion light years away.

Professor Thorne is an accomplished author of books for scientists and the general public, and he was the scientific consultant and Executive Producer of the film Interstellar.
