Computerized Classification of Normal and Abnormal Lung Sounds by Multivariate Linear Autoregressive Model

This work proposes multichannel acquisition of lung sounds by a microphone array, feature extraction by a multivariate AR (MAR) model, dimensionality reduction of the feature vectors (FV) by SVD and PCA and, their classification by a supervised neural network. A microphone array of 25 sensors was at...
