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

Distribution-Aware Locality Sensitive Hashing

2013
Locality Sensitive Hashing (LSH) has been popularly used in content-based search systems. There exist two main categories of LSH methods: one is to index the original data in an effective way to accelerate search process; the other one is to embed the high-dimensional data into hamming space and perform bit-wise operations to search similar objects. In

LOCALIZED SENSITIVITY TO CRUDE PENICILLIN

Archives of Dermatology and Syphilology, 1946
In October 1943 Robinson and Wallace1reported on the use of penicillin-inoculated gauze pads for topical application in the treatment of various superficial infections. Since that time there has been considerable use of crude penicillin in compresses and in ointment bases for the treatment of superficial pyogenic dermatologie diseases.

Bit Reduction for Locality-Sensitive Hashing

IEEE Transactions on Neural Networks and Learning Systems
Locality-sensitive hashing (LSH) has gained ever-increasing popularity in similarity search for large-scale data. It has competitive search performance when the number of generated hash bits is large, reversely bringing adverse dilemmas for its wide applications.
