Nilabja Guha Texas A&M University
My current research at Texas A&M University is in a broad area of uncertainty quantification (UQ), with applications to inverse problems, transport based filtering, graphical models and online learning. My research projects are motivated by many real-world problems in engineering and life sciences. In my current postdoctoral position in the Institute for Scientific Computation (ISC) at Texas A&M University, I have worked with Professor Bani K. Mallick from the department of statistics and Professor Yalchin Efendiev from the department of mathematics. I have collaborated with researchers in engineering and bio-sciences on developing rigorous uncertainty quantification methods within the Bayesian

In these problems, which arise in many petroleum and hydrology applications, the forward problems are compu- tationally expensive and highly heterogeneous with multiple space and time scales. Developing rigorous uncertainty quantification approaches, which can identify data-relevant scales and entail probabilistic in- terpretation for un-resolved scales is challenging and has been my research goal. On another application in aerospace engineering, my research goal has been developing optimal transport based space situational awareness (SSA) methods to view, understand and predict the physical location of natural and manmade objects in orbit around the Earth, where the main challenges are non–Gaussian distribution, sparsity of observation and, system and observational error. On graphical model related problems, the main focus is on developing robust computationally efficient graph estimation methodology in applications related to determining protein networks. Network estimation methodologies in graphical models depend heavily on the assumptions of Gaussianity and the focus of my work has been on developing robust distribution free approaches. In the online learning application, I have extended a stochastic approximation based predictive recursion algorithm for dependent …show more content…
A hierarchical Bayesian model is developed in the inverse problem setup. The Bayesian approach contains a natural mechanism for regularization in the form of a prior distribution, and a LASSO type prior distribution is used to strongly induce sparseness. We propose a variational type algorithm by minimizing the Kullback–Leibler divergence between the true posterior distribution and a separable approximation. The proposed method is illustrated on several two-dimensional linear and nonlinear inverse problems, e.g., Cauchy problem and permeability estimation problem. The proposed method performs comparably with full Markov chain Monte Carlo (MCMC) in terms of accuracy and is computationally

The University of Maryland, College Park (UMCP) is a vast, state funded college in College Park, Maryland. The college was established in 1856 as Maryland Agricultural College. The five star started in 1989 on a 420 section of land grounds.
Texas A&M University is a great school to attend. They have great places to relax and study along with amazing facilities. Don't make the wrong choice and be left out because it offers so much and has many opportunities for everyone. Texas A&M opened as the state's first public institution of higher learning in 1876. Dedicated to sending Aggie leaders out into the world to take the challenges of tomorrow, A&M stands as a research-intensive flagship university.
When Norse F. Rabalais who was born and raised in Simmersport, Louisiana (Avoyelles Parish) was a child there was no navigation lock to lower ships to the Mississippi, the water just poured out, ships with it, and flowed into the distributary known as Atchafalaya. A lot of parishes above New Orleans and quite a bit north of Baton Rouge (Louisiana’s capital) there’s a navigation lock in Mississippi’s bank allows ships to drop out of the river. Because of nature, they drop up to thirty-three feet then can go west or south. This is something very strange and rare between the river and its adjacent terrain. That adjacent terrain is known as Cajun country. The local parishes are Pointe Coupee Parish and Avoyelles parish.
While attending Liberty Univeristy, I started out as a Business Major, but after a few accounting classes I decided to be an Accountant. Not only did I find a career path at Liberty, but I also found my life's mate. We have been married for 34 year and our proudest accomplishment in life are our three children. Nathan, recently married and lives in Wisconsin. Both are clinical pharmacists in the hospital setting. Nathan published his first article for the Pharmacy Journal which started sibling riviary. Lauren, is the Production Manager for the White House Historical Association and could't wait to tell her brother that she published two articles. We also visited the White House on several occasions. Our youngest,
Survey that the commence structure in (1) can be deciphered as section astute low-dimensional representation for each illustration; as needs be it can be speedily acclimated to fit our demand. Specifically, we settle (3) for the entire dataset, and utilize the start system W0 as the novel representation and support it into the data section module, with the subscript "0" demonstrating the entire dataset. It is critical that here we support using W0 over customary name change strategies, for instance, CPLST [32] for the going with reasons: 1) the proposed procedure does not rely on upon the certifiable stamp system Y as in the arrangement of CPLST, and 2) test relationship can be unequivocally introduced, which is proper for data distribute. Our approach makes no particular doubts on the choice of section counts, in this way unique procedures can be considered, including k-suggests gathering, area tricky hashing (LSH), and some flexible systems, for instance, Affinity Propagation batching or ISODATA , if satisfactory prior learning is available. In our execution, we use k-suggests gathering for its straightforwardness and
“Give me an Army of West Point graduates and I'll win a battle... Give me a handful of Texas Aggies and I'll win a war.”- George S. Patton, Jr. West Texas A&M University (WTAMU) is a school with a strong sense of pride. WTAMU is affordable, has high acceptance ratings, teaches what I want to learn, and is not far from where I live. WTAMU is the best college for me to attend to become a computer engineer.

Prairie view A&M university was founded in the year 1876. Prairie view was the first supported college in Texas for African Americans. It was founded as part of the post-civil war effort to restructure education in the state of Texas.
My college is southern methodist university in Dallas, TX which is 181 miles from home. Southern methodist university is 234 ares wide and has approximately 11,739 student enrolled there.They are ranked on of the nation's most prestigious institutions of higher education. They were founded in 1911 by the Methodist Episcopal church.
Pomona College was fused on October 14, 1887, by a gathering of Congregationalists who needed to reproduce on the West Coast "a school of the New England sort," one that would speak to the absolute best of what they had encountered as understudies in the finest universities of the Eastern and Midwestern United States.
“The final quarter of the Men’s Lacrosse National Championship between Notre Dame and Maryland, here at Gillette Stadium in Boston Massachusetts.” Says the announcer as we take our spots on the field, and wait for the game to start.
In 1954 ACSM (American College of Sports Medicine) was founded. It is the largest sports medicine and exercise science program in the world. The ACSM was started by people who want to change the lifestyles of others and help make them healthier; they ACSM program has over 50,000 members. Their members put their knowledge and training into helping others gain a healthier life. As students we are provided opportunities through ACSM. Some of the opportunities we are provided are, resources to extend our learning, for example you could contact a professional in the field that you wish to learn more about. ACSM also offers many employment opportunities as well as being able to attend or present your information at a Conference. Not only do ACSM offer those opportunities but they offer scholarships as well. One of the initiatives ACSM has is called, Everybody Walk, it is a
Uncertainty is ubiquitous and accompanies all events in the real world. It covers all fields of scientific studies, and is inevitable in many aspects of decision making [28]. The essence of uncertainty is the lack of complete knowledge at the time a decision must be made [7]. Uncertainty arises from different sources in various forms, and complicates and affects decision making [28]. Even worse, it may
