Which of the following methods is used to convert categorical variables into a format that can be provided to machine learning algorithms to improve model performance?

  • One-Hot Encoding
  • Principal Component Analysis (PCA)
  • K-Means Clustering
  • Regression Analysis
One-Hot Encoding is a technique used to convert categorical variables into a binary format that machine learning algorithms can understand. It helps prevent a categorical variable's values from being treated as ordinal and is essential for improving the performance of models that use categorical data.
