Heart sound signal classification using fast independent component analysis

Heart sound signal classification using fast independent component analysis

The analysis of heart sound signals is a basic method for heart examination. It may indicate the presence of heart disorders and provide clinical information in the diagnostic process. In this study, a novel feature dimension reduction method based on independent component analysis (ICA) has been proposed for the classification of fourteen different heart sound types; the method was compared wi...

Independent Component Analysis and Its Applications to Sound Signal Separation

EEG classification using generative independent component analysis

We present an application of independent component analysis (ICA) to the discrimination of mental tasks for EEG-based brain computer interface systems. ICA is most commonly used with EEG for artifact identification with little work on the use of ICA for direct discrimination of different types of EEG signals. By viewing ICA as a generative model, we can use Bayes’ rule to form a classifier. We ...

Denoising of Ecg Signal Using Adaptive Independent Component Analysis

It has been observed that denoising of ECG is done in stationary condition i.e. when the patient under scanner is lying on bed or in rest condition. This is very common case and the noise added in this condition can be removed by many different methodologies like FFT, wavelet, ICA etc. However, when the ECG is monitored in dynamic condition e.g., on tread mill testing, the noise inserted due to...

Classification of Alzheimer′s Disease Using Nonlinear Independent Component Analysis

The goal of this study is to classify magnetic resonance imaging (MRI) of brains of patients with Alzheimer′s Disease (AD) and those without AD and then to identify changes in brain MRI in early stages of AD. A novel approach based on the diffusion map framework, which is considered to be one of the leading manifold learning methods, is used for this classification. Diffusion mapping provides d...
