Princip Component Analysis (PCA) is a statistical technique used to reduce te number of variables in a dataset while reserving as much information as possible. It simpfies complex data, making it easier to analyze and visualize. This article provides a practial overview of appliying PCA for dimensionality reduction.

Understanding Principal Component Analysis

PCA transformátory originail variables into new uncorrelated variables called principal acredients. These consultents are ordered so that that that the firtt few retain mogt of thee variation present in thae original data. This process helps in identifying patterns and reducing noise.
