Non-Negative Low Rank Graph Embedding Algorithm

open access: yesJisuanji kexue yu tansuo, 2020
The existing non-negative matrix factorization (NMF) algorithms still have some shortcomings. On one hand, the NMF method calculates its low-dimensional representation directly on the high-dimensional original image data set, but in fact the effective ...

Link-first based quick coordinated virtual network embedding algorithm

open access: yesTongxin xuebao, 2015
In order to reduce costs of link embedding and increase revenue, a coordinated embedding algorithm based on link-first is proposed. The algorithm embeds link and node alternately, and embeds the virtual link that with greater band-width requirement first

Time-Scale Invariant Audio Data Embedding

open access: yesEURASIP Journal on Advances in Signal Processing, 2003
We propose a novel algorithm for high-quality data embedding in audio. The algorithm is based on changing the relative length of the middle segment between two successive maximum and minimum peaks to embed data.

Virtual Network Embedding Based on Topology Potential

open access: yesEntropy, 2018
To improve the low acceptance ratio and revenue to cost ratio caused by the poor match between the virtual nodes and the physical nodes in the existing virtual network embedding (VNE) algorithms, we established a multi-objective optimization integer ...

LOCAL LINEAR EMBEDDING ALGORITHM FOR PARAMETER MATRIX MEASUREMENT IN SYMMETRIC POSITIVE DEFINITE MANIFOLD (MT)

open access: yesJixie qiangdu, 2022
Most of the existing local linear embedding algorithms assume that the original data set is located in Euclidean space, but in reality almost all the original space is non-Euclidean space.

A feasible k-means kernel trick under non-Euclidean feature space

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2020
This paper poses the question of whether or not the usage of the kernel trick is justified. We investigate it for the special case of its usage in the kernel k-means algorithm.
