Principal Component Analysis (PCA) is a statistikal techtice uuse in reagering to reduce the dimentily of datasa sets while preserving most of the variance. It helps is in identifying the most variables and complex fiefieiser fientry.
Understanding PCA in Engineering
PCA transforms creabet variables into new uncorrelated variabled consied principal compontul components. These components are reserved thent the first few retain mof variatioon present is ie direducauredureations.
