A New Approach to Exact Crossing Minimization
The crossing number problem is to find the smallest number of edge crossings necessary when drawing a graph into the plane. Eventhough the problem is NP-hard, we are interested in ...

Estimating correspondence between multiple cameras using joint invariants
The joint invariants of the projective group PSL(3, R) on RP2 , the five-point volume cross-ratios, are studied to address the problem of correspondence in a camera network. The ...

How much feedback overhead is required for base station cooperative transmission to outperform non-cooperative transmission?
Coherent base station (BS) cooperative transmission provides high spectrum efficiency for cellular systems when channel state information (CSI) is perfectly known at the BSs. For...

A low variance error boosting algorithm
Abstract. This paper introduces a robust variant of AdaBoost, cwAdaBoost, that uses weight perturbation to reduce variance error, and is particularly effective when dealing with da...
