Techniques to prevent overfitting by adding constraints or penalties to the model (L1, L2, dropout, early stopping).

3 stops · basics first
  1. Dataset ✓ understood

    A collection of data examples used for training, validating, or testing machine learning models.

  2. Training Data ✓ understood

    The examples a model learns its weights from, kept separate from the validation and test data used to check how well it generalizes.

  3. Overfitting ✓ understood

    When a model fits its training data too closely, noise included, so it scores well on examples it has seen and poorly on new ones.

Picture it

Penalize weights

  • L2 adds λ·Σw² to the loss
  • L1 adds λ·Σ|w|, pushing weights to zero
  • Weight decay shrinks weights each step

Inject noise

  • Dropout zeroes random units in training
  • Data augmentation varies the inputs

Stop early

  • Watch validation loss during training
  • Keep the checkpoint where it bottoms out
Notice how every technique limits how closely the model can fit noise in the training data, trading a bit of fit for better generalization.
