An Improved DQDS Algorithm [PDF]
SIAM Journal on Scientific Computing, 2014 In this paper we present an improved dqds algorithm for computing all the singular values of a bidiagonal matrix to high relative accuracy. There are two key contributions: a novel deflation strategy that improves the convergence for badly scaled matrices, and some modifications to certain shift strategies that accelerate the convergence for most ...

Improving the Quickprop algorithm [PDF]
The 2012 International Joint Conference on Neural Networks (IJCNN), 2012 Backpropagation (BP) algorithm is the most popular supervised learning algorithm that is extensively applied in training feed-forward neural networks. Many BP modifications have been proposed to increase the convergence rate of the standard BP algorithm, and Quickprop is one the most popular fast learning algorithms.

An Improved CURE Algorithm [PDF]
, 2018 CURE algorithm is an efficient hierarchical clustering algorithm for large data sets. This paper presents an improved CURE algorithm, named ISE-RS-CURE. The algorithm adopts a sample extraction algorithm combined with statistical ideas, which can reasonably select sample points according to different data densities and can improve the representation of

Self-Improving Algorithms [PDF]
SIAM Journal on Computing, 2011 We investigate ways in which an algorithm can improve its expected performance by fine-tuning itself automatically with respect to an unknown input distribution D. We assume here that D is of product type. More precisely, suppose that we need to process a sequence I_1, I_2, ...

Improving the Expected Improvement Algorithm
CoRR, 2017 The expected improvement (EI) algorithm is a popular strategy for information collection in optimization under uncertainty. The algorithm is widely known to be too greedy, but nevertheless enjoys wide use due to its simplicity and ability to handle uncertainty and noise in a coherent decision theoretic framework. To provide rigorous insight into EI, we

Designing LED array for uniform illumination based on local search algorithm [PDF]
Journal of the European Optical Society-Rapid Publications, 2014 We propose a numerical optimization method based on local search algorithm to design an LED array for a highly uniform illumination distribution. In the first place, an initial LED array is randomly generated and the corresponding value of the objective ...

Improved Fast-HotStuff Blockchian Consensus Algorithm [PDF]
Jisuanji gongcheng, 2021 The consensus process of the Fast-HotStuff blockchain consensus algorithm consists of two rounds of voting. When the leader node fails after the first round of voting, the throughput will be greatly reduced.
