Model Selection Through Sparse Maximum Likelihood Estimation
We consider the problem of estimating the parameters of a Gaussian or binary distribution in such a way that the resulting undirected graphical model is sparse. Our approach is to...

Content Distribution in VANETs Using Network Coding: The Effect of Disk I/O and Processing O/H
Abstract—Besides safe navigation (e.g., warning of approaching vehicles), car to car communications will enable a host of new applications, ranging from office-on-the-wheel supp...

Fourier signature in log-polar images
Abstract. In image-based robot navigation, the robot localises itself by comparing images taken at its current position with a set of reference images stored in its memory. The pro...

Scalable communication protocols for dynamic sparse data exchange
Many large-scale parallel programs follow a bulk synchronous parallel (BSP) structure with distinct computation and communication phases. Although the communication phase in such ...
