Robust random cut forest based anomaly detection on streams

S Guha, N Mishra, G Roy… - … conference on machine …, 2016 - proceedings.mlr.press
In this paper we focus on the anomaly detection problem for dynamic data streams through
the lens of random cut forests. We investigate a robust random cut data structure that can be …

Near-optimal hashing algorithms for approximate nearest neighbor in high dimensions

A Andoni, P Indyk - Communications of the ACM, 2008 - dl.acm.org
In this article, we give an overview of efficient algorithms for the approximate and exact
nearest neighbor problem. The goal is to preprocess a dataset of objects (eg, images) so …

[書籍][B] Distributed computing: a locality-sensitive approach

D Peleg - 2000 - SIAM
Distributed computing concerns environments in which many processors, located at different
sites, must operate in a noninterfering and cooperative manner. Each of the processors …

A tight bound on approximating arbitrary metrics by tree metrics

J Fakcharoenphol, S Rao, K Talwar - … of the thirty-fifth annual ACM …, 2003 - dl.acm.org
In this paper, we show that any n point metric space can be embedded into a distribution
over dominating tree metrics such that the expected stretch of any edge is O (log n). This …

Multiway spectral partitioning and higher-order cheeger inequalities

JR Lee, SO Gharan, L Trevisan - Journal of the ACM (JACM), 2014 - dl.acm.org
A basic fact in spectral graph theory is that the number of connected components in an
undirected graph is equal to the multiplicity of the eigenvalue zero in the Laplacian matrix of …

Optimal hierarchical decompositions for congestion minimization in networks

H Räcke - Proceedings of the fortieth annual ACM symposium on …, 2008 - dl.acm.org
Hierarchical graph decompositions play an important role in the design of approximation
and online algorithms for graph problems. This is mainly due to the fact that the results …

and Theoretical Computer Science that focuses on problems arising in the realm of modern …

Algorithmic applications of low-distortion geometric embeddings

P Indyk - Proceedings 42nd IEEE Symposium on Foundations …, 2001 - ieeexplore.ieee.org
The author surveys algorithmic results obtained using low-distortion embeddings of metric
spaces into (mostly) normed spaces. He shows that low-distortion embeddings provide a …

Strengthening integrality gaps for capacitated network design and covering problems

RD Carr, LK Fleischer, VJ Leung, CA Phillips - 1999 - osti.gov
A capacitated covering IP is an integer program of the form min {l_brace} ex {vert_bar} Ux
{ge} d, 0 {le} x {le} b, x {element_of} Z {sup+}{r_brace}, where all entries of c, U, and d are …
