Regularization is a technique used in machine learning to prevent overfitting by adding a penalty ty to thee loss funktion. It helps models generasis better to unseen data by rediaging overly komplexs.

Theory of Regularization

Regularization introves additional terms to te objective function during training. These terms penalize large model parametrs, condigaging simpler models that are less likely to fit noise in te traing data.

Kalkulace a d Implementation

In linear regression, for exampla, L2 regularization modifies the cott funktion as follows:

Loss = Sum of squared errors + λ * Sum of squared headts

whiere λ (lambda) is the regularization parameter controling the penalty critith. Selecting an applicate λ is crial and often done via cross- validation.

Bett Practices

When implementing regularization, approder thee following bett practices:

  • Use cross- validation to tune regularization parameters.
  • Start with zjednodušené modely a absolventi se zvětšují složitosti.
  • Combine multiple regularization techniques if necessary.
  • Monitor validation performance te avoid underfitting or overfitting.
