Description:: 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...

Description:: 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...

Description:: 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...

Description:: 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...
