Applying your skills
Module 7 key takeaways
- Optimisation is key for efficient and effective ML: Understanding and applying core training techniques like gradient descent and regularisation, along with various optimisation algorithms, is crucial for building efficient, high-performing models that generalise well.
- Advanced strategies drive superior model performance: Hyperparameter tuning, ensemble learning, and model calibration help maximise performance, robustness, and reliability for trustworthy predictions.
- Robust data handling ensures ethical and reliable outcomes: Reliable splits and validation, imbalanced-data techniques, and data-quality practices reduce leakage and bias and support ethical deployment.
