**2010年度第4回 [#sc26d268]

日時: ''2010年11月15日(月) 11:00-12:00''

会場: ''西8号館W棟8階W809号室''

講演者: ''Michael Bowling 氏 (Department of Computing Science, University of Alberta)''

題目: ''AI After Dark: Computers Playing Poker''

要旨:

The game of poker presents a serious challenge for artificial
intelligence. The game is essentially about dealing with many forms of
uncertainty: unobservable opponent cards, undetermined future cards,
and unknown opponent strategies. Coping with these uncertainties is
critical to playing at a high-level.  In July 2008, the University of
Alberta's poker playing program, Polaris, became the first to defeat
top professional players at any variant of poker in a meaningful
competition. In this talk, I'll tell the story of this match
interleaved with the science that enabled Polaris's accomplishment.

**2010年度第3回 [#sc26d268]

日時: ''2010年9月9日(木) 14:00-15:00''

会場: ''西8号館W棟8階W809号室''

講演者: ''Anders Hanson 氏 (Department of Electrical Engineering, Linkopings Universitet)''

題目: ''A Structure Exploiting Preprocessor for Semidefinite Programs derived from the Kalman-Yakubovich-Popov Lemma''

要旨:

Semidefinite programs derived from the Kalman-Yakubovich-Popov
(KYP) lemma are quite common in control and signal processing
applications. The programs are often of high dimension which makes them
hard or impossible to solve with general-purpose solvers. Here we
present a customized preprocessor, KYPD, that utilizes the inherent
structure of this particular optimization problem. The key to an
efficient implementation is to transform the optimization problem into
an equivalent semidefinite program. This equivalent problem has much
fewer variables and the matrices in the linear matrix inequality
constraints are of low rank. KYPD can use any primal-dual solver for
semidefinite programs as an underlying solver.

**2010年度第2回 [#sc26d268]

日時: ''2010年7月6日(火) 16:30-17:30''

会場: ''西8号館W棟8階W809号室''

講演者: ''Tien-Yien Li 氏 (Department of Mathematics, Michigan State University)''

題目: ''The story about chaos''

要旨:

The talk mainly contains my personal contacts with those
heavy weights in Chaos, including Japanese Attractor and its author Ueda
of course.

**2010年度第1回 [#sc26d268]

日時: ''2010年5月6日(木) 13:20-14:50''

会場: ''西8号館W棟8階W809号室''

講演者: ''Lang Wu 氏 (University of British Columbia)''

題目: ''Joint inference of longitudinal data and survival data in the
presence of measurement errors''

要旨:

We consider a joint model for a nonlinear mixed effects model and a
survival model in the presence of covariate measurement errors. We
estimate all model parameters simultaneously based on Laplace
approximation as well as the commonly-used Monte-Carlo EM algorithm.
The models and methods are motivated and illustrated by a study on HIV
viral dynamics.
