What is tuning in machine learning?

Model tuning bridges raw capability and real-world performance.
Jeff Dean

How It Works:

Tuning adjusts hyperparameters (like learning rate, batch size, regularization strength) to find the best combination that maximizes model performance.

Key Benefits:

  • Unlocks higher accuracy
  • Controls overfitting and underfitting
  • Optimizes resource usage

Real-World Use Cases:

  • Grid or random search for small models
  • Bayesian optimization for large training runs
