Wager , Department of Psychology & Neuroscience , University of Å·ÃÀ¿Ú±¬ÊÓƵ at Boulder Location Information: Main Campus - Engineering Classroom Wing ( View Map ) 1111 Engineering DR Boulder, CO Room: 265 Contact Information: Name: Ian Cunningham Phone: 303-492-4668 Email: amassist@colorado.edu

Event Description: Radu Craiu , Department of Statistical Sciences , University of Toronto Adaptive Strategies for Component-Wise Metropolis-Hastings Adaptive ideas within the MCMC universe are ubiquitous. However, proving the validity of an adaptive MCMC sampler can be a complicated affair, especially because of the so-called Containment Condition. Recent theoretical developments...

Event Description: R. Tyrell Rockafellar , Department of Mathematics , University of Washington Risk, Optimization and Statistics Uncertainty over the future, even if well supported by statistical information, causes a fundamental difficulty in optimization. Decisions can't pin future "costs" to specific values and are instead limited only to shaping their...

Event Description: John Hunter ; Department of Mathematics ; University of California, Davis Nonlinear surface plasmons Surface plasmons (SPs) are electromagnetic surface waves that propagate on the interface between an insulator and a conductor, such as air and gold. At short wavelengths, the frequency of SPs approaches a nonzero constant...
