Surveillance Event Detection
We have developed and evaluated three generalized systems for event detection. The first system is a simple brute force search method, where each space-time location in the video ...

Pebbling and Branching Programs Solving the Tree Evaluation Problem
We study restricted computation models related to the tree evaluation problem. The TEP was introduced in earlier work as a simple candidate for the (very) long term goal of separa...

Adaptive k-Nearest-Neighbor Classification Using a Dynamic Number of Nearest Neighbors
Classification based on k-nearest neighbors (kNN classification) is one of the most widely used classification methods. The number k of nearest neighbors used for achieving a high ...

Scapegoat Trees
We present an algorithm for maintaining binary search trees. The amortized complexity per INSERT or DELETE is O(log n) while the worst-case cost of a SEARCH is O(log n). Scapegoat...

Max registers, counters, and monotone circuits
A method is given for constructing a max register, a linearizable, wait-free concurrent data structure that supports a write operation and a read operation that returns the larges...
