4 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.

  4. Data Augmentation ✓ understood

    Creating variations of training data through transformations (rotation, cropping, noise) to improve model generalization.

  5. Mixup · you are here ✓ understood

Data augmentation creating synthetic examples by interpolating between training examples and their labels.

This concept is essential for understanding training & optimization and forms a key part of modern AI systems.
