Computing Exponentials of Essentially Non-negative Matrices with Entry-wise Accuracy

Speaker: Qiang Ye, University of Kentucky

Abstract:

A real square matrix is said to be essentially non-negative if all of its off-diagonal entries are non-negative. In this talk, I will present new perturbation results and algorithms that demonstrate that the exponential of an essentially non-negative matrix can be computed with entrywise relative accuracy.

There has been a Chinese population in Cambodia for more than 500 years and contact with Cambodia was first mentioned by the eminent China emissary Zhou Daguan as early as 1296 during his travels there. Despite a relatively high degree of integration into to the majority Cambodia culture, ethnic Chinese have maintained their own social organizations, news media, and schools.  The Cambodian Chinese population is organized around five Huiguan (会馆) ‘congregations’  corresponding to the southern-origin Chinese groups that comprise it: Chaozhou 潮州会馆,  Cantonese 广肇会馆，Hakka 客属会馆, Fujian 福建会馆, and Hainan 海南会馆.  Until the Khmer Rouge forced closure of Chinese schools in the mid seventies, the language of Chinese education followed the dialects of each association.  However, in recent times Mandarin has become the lingua franca of the Sino-Cambodia community, though among ethnic Chinese there are few if any native speakers of Mandarin.

Through examination of survey data and recorded interviews, this presentation sketches a picture of the contemporary Chinese community in Cambodian and outlines some of the language change occurring by contact with the majority Khmer langauge. The paper gives special attention to examples from the local Cantonese.

Kirk examines the contrasting circumstances surrounding the inception and fate of two great colonial Mexican libraries to illuminate the gender politics of knowledge at play in the intellectual culture of seventeenth-century New Spain. Sor Juana Inés de la Cruz, cloistered nun and famous writer, used her vast collection of books to challenge women's exclusion from scholarly culture while Bishop Juan de Palafox y Mendoza, powerful colonial political and religious figure, placed his library at the center of a powerful educational institution which promoted the production and dissemination of knowledge as masculine. 

This Wednesday, Andrew and Brenna Byrd will explain in detail their incredible journey back in time with Ubisoft's game "Far Cry: Primal." They will describe the process of creating two entire languages based off of Indo-European, how they trained the actors and worked with the directors and writers off and on set, and what they hope this exposure means for the field of historical linguistics. Additionally, there will be a short lesson in Wenja (the main language of the game), a scene reenactment with two talented theater students to show the filming process, and two copies of the game to raffle off to attendees.

Eric Beaty – Economic and Commercial Attaché

United States Consulate for Western France

 

Born in Sapulpa, Oklahoma on October 21, 1958, Eric Beaty grew up in Nacogdoches, Texas.  He graduated from Nacogdoches High School in 1976 and did his undergraduate studies at Stephen F. Austin University in Nacogdoches, earning a B.A. (Cum Laude - 1979) with a double major in French and German and a minor in history.  He went on to earn an M.A. in French literature at Rice University in Houston, Texas (1982).  Later, Beaty received an Msc. in Linguistics from Aston University in Birmingham, U.K. (1996).

Beaty began his career at the University of Rennes 2, France in 1981 as a lecturer in American studies.  He then worked as the assistant director of courses at two Chambers of Commerce in France.  In 1986, Beaty became the executive director of a bi-national center known as the Franco-American Institute, an organization created by Rennes City Hall, the U.S. Embassy in Paris and Rochester, N.Y. City Hall in 1961. 

In 1999, Beaty was instrumental in setting up the United States Consulate for Western France. He was hired in 2000 by the U.S. State Department that same year as the Economic and Commercial Attaché. 

Beaty has participated in the organization of 14 White House visits and 36 congressional delegation visits.  He has chaired the Rennes-Rochester, N.Y. sister-city relationship since 1986.   He is on the board of the University of Rennes 2.  Beaty has received 18 meritorious and superior service awards from the White House, the U.S. State Department and the U.S. Department of Commerce.  Beaty received a National Export Initiative award for his export success stories in 2011.   

Learning Algorithms for Restricted Boltzmann Machines

Speaker: Devin Willmott, University of Kentucky

Abstract: Restricted Boltzmann machines (RBMs) have played a central role in the development of deep learning. In this talk, we will introduce the theoretical framework behind stochastic binary RBMs, give motivation and a derivation for the most commonly used RBM learning algorithm (contrastive divergence), and prove some analytic results related to its convergence properties.

I will describe the process by which SDSS/APOGEE data are analyzed to provide stellar parameters and abundances, and present how these are available in public data releases. I'll then do a quick tour through a range of science topics that have been addressed with the APOGEE data.
