Principal Component Analysis (PCA) PCAreplaces Xwith a lower-dimensional approximation Z. Matrix Zhas nrows, but typically far fewer columns. PCA is used for: Dimensionality reduction: replace Xwith a lower-dimensional Z. Outlier detection: if PCA gives poor approximation of xi, could be outlier The essential purpose of Factor Analysis is to describe the covariance relationships between several variables in terms of a few underlying and unobservable random components that we will call factors.

In machine learning we are having too many factors on which the final classification is done.These factors are b asically, known as variables. The higher the number of features, the harder it gets to visualize the training set and then work on it. Sometimes, most of these features are correlated, and hence redundant.This is where dimensionality reduction algorithms come into play Risk factors analysis of COVID-19 patients with ARDS and prediction based on machine learning Application in Machine Learning. Correlation is a highly applied technique in machine learning during data analysis and data mining. It can extract key problems from a given set of features, which.
