Adversarial Examples for k-Nearest Neighbor Classifiers Based on Higher-Order Voronoi Diagrams

no code implementations NeurIPS 2021 Chawin Sitawarin, Evgenios M. Kornaropoulos, Dawn Song, David Wagner

On a high level, the search radius expands to the nearby higher-order Voronoi cells until we find a cell that classifies differently from the input point.

Optimizing Static and Adaptive Probing Schedules for Rapid Event Detection

no code implementations8 Sep 2015 Ahmad Mahmoody, Evgenios M. Kornaropoulos, Eli Upfal

We formulate and study a fundamental search and detection problem, Schedule Optimization, motivated by a variety of real-world applications, ranging from monitoring content changes on the web, social networks, and user activities to detecting failure on large systems with many individual machines.
