Deterministic sampling and range counting in geometric data streams
We present memory-efficient deterministic algorithms for constructing -nets and -approximations of streams of geometric data. Unlike probabilistic approaches, these deterministic...

Geometric Clustering Using the Information Bottleneck Method
We argue that K–means and deterministic annealing algorithms for geometric clustering can be derived from the more general Information Bottleneck approach. If we cluster the ide...

Fast Geometric Routing with Concurrent Face Traversal
We present a concurrent face routing CFR algorithm. We formally prove that the worst case latency of our algorithm is asymptotically optimal. Our simulation results demonstrate tha...

Registration of 2D Points Using Geometric Algebra and Tensor Voting
In this paper, we present a novel algorithm that combines the power of expression of Geometric Algebra with the robustness of Tensor Voting to find the correspondences between two...
