Parametric optimization for multi-layered filament-wound cylinder based on hybrid method of GA-PSO coupled with local sensitivity analysis

Composite structures, 2021
Filament-wound cylinder always demonstrates diverse performances due to the different designed parameters. This paper aims to provide a hybrid method for optimizing the winding angle and fiber volume content of a composite cylinder under internal ...

Kernelized Locality-Sensitive Hashing

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2012
Fast retrieval methods are critical for many large-scale and data-driven vision applications. Recent work has explored ways to embed high-dimensional features or complex distance functions into a low-dimensional Hamming space where items can be efficiently searched.

Global and local sensitivity analysis to improve the understanding of physically-based urban wash-off models from high-resolution laboratory experiments.

Science of the Total Environment, 2019
Physically-based urban wash-off models are a promising means of studying the transport of finer suspended solids and their associated pollutants during rain events, considering spatial and temporal heterogeneities.

Distributed Locality Sensitivity Hashing

2010 7th IEEE Consumer Communications and Networking Conference, 2010
In this paper, we present DLSH Distributed Locality Sensitive Hashing, a similar-data search technology. The huge growth in the size of video content has broken the traditional multi-media index hosting and look-up solutions, these are not able to scale to the size of the current and projected index requirements.

In Defense of Locality-Sensitive Hashing

IEEE Transactions on Neural Networks and Learning Systems, 2018
Hashing-based semantic similarity search is becoming increasingly important for building large-scale content-based retrieval system. The state-of-the-art supervised hashing techniques use flexible two-step strategy to learn hash functions. The first step learns binary codes for training data by solving binary optimization problems with millions of ...

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.

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.

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 ...
