SVM Intrusion Detection Model Based on Compressed Sampling

open access: yesJournal of Electrical and Computer Engineering, 2016
Intrusion detection needs to deal with a large amount of data; particularly, the technology of network intrusion detection has to detect all of network data.

Combinatorial Regression and Improved Basis Pursuit for Sparse Estimation [PDF]

open access: yes, 2012
Sparse representations accurately model many real-world data sets. Some form of sparsity is conceivable in almost every practical application, from image and video processing, to spectral sensing in radar detection, to bio-computation and genomic signal ...

Sample Distortion for Compressed Imaging [PDF]

open access: yesIEEE Transactions on Signal Processing, 2013
We propose the notion of a sample distortion (SD) function for independent and identically distributed (i.i.d) compressive distributions to fundamentally quantify the achievable reconstruction performance of compressed sensing for certain encoder-decoder pairs at a given sampling ratio.

BREAKING THE COHERENCE BARRIER: A NEW THEORY FOR COMPRESSED SENSING

open access: yesForum of Mathematics, Sigma, 2017
This paper presents a framework for compressed sensing that bridges a gap between existing theory and the current use of compressed sensing in many real-world applications.

An Enhanced Photonic-Assisted Sampling Approach for Spectrum-Sparse Signal by Compressed Sensing

open access: yesIEEE Access, 2022
Spectrum-sparse signals are vital for wideband radar and wireless communication applications. A high-speed analog-to-digital converter (ADC) with the capacities of tens of gigahertz sampling rates is often required to acquire these signals. In this work,

A survey of potential sampling strategies for measurement of structured surfaces. [PDF]

open access: yes, 2009
Uniform sampling is the predominant sampling method for surface measuring instruments. However, measurement for structured surfaces brings an increasingly serious conflict between sampling range and small resolution.

Fault Diagnosis of a Propeller Using Sub-Nyquist Sampling and Compressed Sensing

open access: yesIEEE Access, 2022
The fault diagnosis of rotating machinery is generally performed using methods that employ vibration and sound. These methods are simple and accurate. However, all of these methods measure vibration data on the basis of the sampling theorem.

Low Complexity Cyclic Feature Recovery Based on Compressed Sampling

open access: yesInternational Journal of Distributed Sensor Networks, 2015
To extract statistic features of communication signal from compressive samples, such as cyclostationary property, full-scale signal reconstruction is not actually necessary or somehow expensive. However, direct reconstruction of cyclic feature may not be

Imaging via Compressive Sampling [PDF]

open access: yesIEEE Signal Processing Magazine, 2008
Image compression algorithms convert high-resolution images into a relatively small bit streams in effect turning a large digital data set into a substantially smaller one. This article introduces compressive sampling and recovery using convex programming.

Compressed Sensing with nonlinear observations and related non-linear optimisation problems

open access: yes, 2013
Non-convex constraints have recently proven a valuable tool in many optimisation problems. In particular sparsity constraints have had a significant impact on sampling theory, where they are used in Compressed Sensing and allow structured signals to be ...
