Comparative study for broadband direction of arrival estimation techniques [PDF]

open access: yes, 2012
This paper reviews and compares three different linear algebraic signal subspace techniques for broadband direction of arrival estimation --- (i) the coherent signal subspace approach, (ii) eigenanalysis of the parameterised spatial correlation matrix ...

EEF: Exponentially Embedded Families with Class-Specific Features for Classification

open access: yes, 2016
In this letter, we present a novel exponentially embedded families (EEF) based classification method, in which the probability density function (PDF) on raw data is estimated from the PDF on features.

Classification of ultrasonic signals [PDF]

open access: yesInternational Journal of Materials and Product Technology, 2006
In ultrasonic non-destructive testing it is very difficult to detect flaws in materials with coarse-grain structure. The ultrasonic signals measured on these materials contain echoes which are very similar to fault echoes. These echoes arise from grains which are contained in the material.

ECG Arrhythmia Classification Using Transfer Learning from 2-Dimensional Deep CNN Features

open access: yes, 2018
Due to the recent advances in the area of deep learning, it has been demonstrated that a deep neural network, trained on a huge amount of data, can recognize cardiac arrhythmias better than cardiologists.

Improved VMD‐KFCM algorithm for the fault diagnosis of rolling bearing vibration signals

open access: yesIET Signal Processing, 2021
In order to make accurate judgements of rolling bearing main fault types using the small sample size fault data set, a novel approach is put forward that combines particle swarm optimisation kernel fuzzy C‐means (PSO‐KFCM) and variational mode ...

A symmetric adaptive visibility graph classification method of orthogonal signals for automatic modulation classification

open access: yesIET Communications, 2023
Visibility graph methods allow time series to mine non‐Euclidean spatial features of sequences by using graph neural network algorithms. Unlike the traditional fixed‐rule‐based univariate time series visibility graph methods, a symmetric adaptive ...
