Marginal Space Learning for Fast Detection in Large Dimensional Spaces

In this paper we present a new computational method for object detection in high dimensional spaces that achieves speedups on the order of millions of times with minimal performance loss. The problem addressed is the large computational burden incurred when detecting objects with many parameters (e.g. 9 parameters for 3D rigid objects). Another problem addressed is that memory limitations prohi...

String Theory: Exact Solutions, Marginal Deformations and Hyperbolic Spaces

Marginal Deformations from Branes

We study brane configurations for four dimensionalN=1 supersymmetric gauge theories with quartic superpotentials which flow in the infrared to manifolds of interacting superconformal fixed points. We enumerate finite N=2 theories, from which a large class of marginal N=1 theories descend. We give the brane descriptions of these theories in Type IIA and Type IIB string theory. The Type IIB descr...

Orbit Spaces Arising from Isometric Actions on Hyperbolic Spaces

Let be a differentiable action of a Lie group on a differentiable manifold and consider the orbit space with the quotient topology.  Dimension of is called the cohomogeneity of the action of  on . If is a differentiable manifold  of  cohomogeneity one under the action of  a compact and connected Lie group, then the orbit space is homeomorphic to one of the spaces , , or . In this paper we suppo...
