This talk summarizes an effort at the Modeling, Simulation and Visualization Center at the University of Wisconsin-Madison to model and simulate large scale discrete dynamics problems. This effort is motivation by a desire to address unsolved challenges posed by granular dynamics problems, mobility of tracked and wheeled vehicle on granular terr...

The web has a vast wealth of information about various types of entities such as businesses (e.g., address, phone, category, hours of operation), products, books, doctors, etc. distributed over a very large number of web sites. Extracting this information from the websites can help us create extensive databases of the entities. These databases c...

In this talk I will discuss the novel experimental designs for large-scale multiple hypothesis testing problems. Testing to determine which genes are differentially expressed in a certain disease is a classic instance of multiple testing in medical informatics. Tremendous progress has been made in high-dimensional inference and testing problems ...

Large-scale optimization, sometimes called 'inverse design' or 'topology optimization,' involves the computational design of new structures that maximize performance of a device, with so many parameters (hundreds, thousands, or more) that the computer is free to 'discover' entirely new geometries rather than simply tweaking a few parameters of a...

We focus on developing a novel scalable graph-based semi-supervised learning (SSL) method for a small number of labeled data and a large amount of unlabeled data. Due to the lack of labeled data and the availability of large-scale unlabeled data, existing SSL methods usually encounter either suboptimal performance because of an improper graph or...

Subspace clustering refers to the problem of clustering data drawn from a union of low-dimensional subspaces of a high-dimensional space. State-of-the-art subspace clustering methods are based on expressing each data point as a linear combination of other data points while regularizing the matrix of coefficients with the L1, L2, or nuclear norms...

We consider a tournament game in which each player is rewarded based on her rank in terms of the time of reaching a goal. We prove existence, uniqueness and stability of the game with in_x000C_finitely many players, existence of an approximate equilibrium with _x000C_finitely many players, and _x000C_find an explicit characterization when player...
