Principal Component Analysis (PCA) is a statistikal techtique uuse to reduce number of variables variables in a dataset while preservaing as much information as possiblee. lt simplefies complex dates, maskinr presereo anize possioclaida.

Memahami Prinsip Komponent Analysis

PCA transforms creabet variables into the start to be recorlated variabled consied constolol components. These components are reserved then then few retaion mof varatiom present ie readnawa data.

PCA PSD TO Apply

  • Ascen1; ASA1; FLT: 0 FLT: 0 variables; Standardize Data: Advan1; FLT: 1: 1 1f 3; Scale variables to have mean of zero and sebuah standard deviatioun one.
  • Pertama; FLT: 0 = 33. Komputer yang berhubungan dengan vary.
  • Callate Eigenvalues and Eigenvectors: legaone; FLT: 1 After3; Deterpe directions of maximum variance.
  • Pertama; FLT: 0 = 33. Selet Principal Components: SOR1; FLT: 1; 1; ASA3; Choope components based on eigenvalueos tont capture the most variance.
  • FLT: 0 = 33; Transform Th Data: 1; FLT: 1 ASA3; Project orista data onto selected components.

Applications Praktis

PCA is widely used in fields such a imagine emansing, bioinformatics, and finance. lt hells in reduccino datka complexity, visualizing higly-dimensionala dala, and immediving the entrice of machine learning model.
