The Overfitting Challenge
Overfitting occurs when a model learns training data too well, including noise and irrelevant patterns, leading to poor generalization. Regularization techniques help models learn meaningful patterns while staying robust to new data.
🎯 Regularization Goals
✓
Prevent overfitting: Stop memorizing training data
✓
Better generalization: Improve validation performance
✓
Reduce complexity: Simpler, more robust models
✓
Handle noise: Ignore irrelevant patterns
❌
Overfitting
Model fits training data too closely
•High train accuracy (99%)
•Low validation accuracy (75%)
•Memorizes noise
✅
Good Fit
Model learns general patterns
•Good train accuracy (93%)
•Similar validation accuracy (91%)
•Generalizes well
🛠️ Regularization Techniques
Dropout
Randomly disable neurons
L1/L2
Penalize large weights
Early Stopping
Stop when val loss increases
