What is regularization in neural networks?

Updated May 17, 2026

Short answer

Regularization reduces overfitting by penalizing model complexity.

Deep explanation

Techniques include L1/L2 regularization, dropout, and early stopping. It constrains weight growth or model capacity.

Real-world example

Used in production ML models to improve generalization.

Common mistakes

  • Over-regularizing leading to underfitting.

Follow-up questions

  • What is L1 vs L2 regularization?
  • What is early stopping?
