PCA stands for Principal Component Analysis, a dimensionality reduction technique used in machine learning.

• PCA is used to transform a dataset into a lower-dimensional space while retaining most of the original information.

• It identifies the directions (principal components) in which the data varies the most.

• The first principal component captures the maximum variance in the data, followed by the second, and so on.

• PCA is commonly used for feature extraction, data visualization, ...read more
