Principal component analysis for time series
WebApr 13, 2024 · Principal component analysis (PCA) is a statistical method that was proposed by Pearson (1901) and independently also by Hotelling (1933) , which consists of describing the variation produced by the observation of p random variables in terms of a set of new variables that are uncorrelated with each other (called principal components), … WebThe principal component analysis helps in classifying VB and BB sound signals through the feature extraction from the power spectral density data. The method proposed in the present work is simple, cost-effective, and sensitive, with a far-reaching potential of addressing and diagnosing the current issue of COVID 19 through lung auscultation.
