Fast locality-sensitive hashing

Proceedings of the 17th ACM SIGKDD international conference on Knowledge discovery and data mining, 2011
Locality-sensitive hashing (LSH) is a basic primitive in several large-scale data processing applications, including nearest-neighbor search, de-duplication, clustering, etc. In this paper we propose a new and simple method to speed up the widely-used Euclidean realization of LSH.

Locality-Sensitive Hashing for Chi2 Distance

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2012
In the past 10 years, new powerful algorithms based on efficient data structures have been proposed to solve the problem of Nearest Neighbors search (or Approximate Nearest Neighbors search). If the Euclidean Locality Sensitive Hashing algorithm, which provides approximate nearest neighbors in a euclidean space with sublinear complexity, is probably ...

On the Local Sensitivity of the Lyapunov Equations

2001
This paper presents a new local perturbation bound for the continuous-time Lyapunov matrix equations, which is not formulated in terms of condition numbers. The new bound is a nonlinear, first order homogeneous function of the absolute perturbations in the data and is sharper than the linear local bounds based on condition numbers.

Ensemble sensitivity localization

2023
Ensemble sensitivity is a tool to quantitatively determine which initial conditions influence a forecast quantity of choice. This information can then be used to understand the sources and dynamics of forecast uncertainty, quantify the impact of observations (e.g., E-FSOI), and determine where to best deploy observations to improve the forecast (e.g ...

Local Sensitivity Analysis

1996
Abstract We review several methods for assessing the effect of small changes to the prior distribution. Our emphasis is on a variety of derivative-like quantities. Some of these have deficiencies that make them unsuitable as diagnostics. We explore the reasons for this and we look at some attempts to avoid these problems.

Reducing sensitivity to localization error through local search

2007 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2007
Many researchers study the search of unknown areas with teams of cooperating robots. Robot cooperation often relies upon shared representations built from shared information. When robots share information, they inadvertently share the error associated with that information. In this research, we realistically assume that all position-based data has some

Local Tensor Completion Based on Locality Sensitive Hashing

2018 IEEE 34th International Conference on Data Engineering (ICDE), 2018
Tensor completion can be applied to fill in the missing data, which is import for many data applications where the data are incomplete. To infer the missing data, existing tensorcompletion algorithms generally assume that the tensor data have global low-rank structure and apply a single model to fit the overall observed data through the global ...

Metabisulfite Sensitivity and Local Dental Anesthesia

Survey of Anesthesiology, 1989
A case of sulfite sensitivity first manifesting as urticaria and acute airway obstruction following local anesthesia is described. A positive parenteral provocation test to metabisulfite was observed weeks after recovery of the patient from the clinical event.

Subcellular Localization of Glutathione and Thermal Sensitivity

Radiation Research, 1988
Chinese hamster ovary (CHO) cells were exposed to various concentrations of diethylmaleate (DEM) during a 42 degrees C incubation to determine if glutathione (GSH) compartmentalization was a factor in modification of thermal sensitivity. Cytoplasmic and mitochondrial GSH were isolated from CHO cells immediately after a hyperthermic treatment consisting

On the non-local sensitivity of Sylvester equations

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
Non-local sensitivity analysis of Sylvester matrix equations is presented. An asymptotically sharp non-local perturbation bound is obtained.
