  "term": "Regularized discriminant analysis",
  "field": "Chemistry",
  "definition": "A statistical classification method that extends linear and quadratic discriminant analysis by introducing regularization parameters. These parameters control the complexity of the covariance matrices, preventing overfitting, especially when the number of variables is large relative to the number of samples. This technique is used to classify observations into predefined groups based on a set of predictor variables.",
