What is Automated Machine Learning (AutoML) in Azure ML?
Updated May 15, 2026
Short answer
Azure AutoML automates algorithm selection, feature engineering, preprocessing, and hyperparameter tuning to build optimized ML models.
Deep explanation
AutoML simplifies machine learning by automatically evaluating multiple models and configurations. It helps users rapidly build accurate models without extensive ML expertise.
Azure AutoML supports:
- Classification
- Regression
- Forecasting
- NLP
- Computer Vision
The system automatically performs:
- Data preprocessing
- Missing value handling
- Feature normalization
- Feature selection
- Algorithm comparison
- Hyperparameter optimization
- Ensemble generation
AutoML is valuable for rapid prototyping, baseline generation, and business users who require low-code ML solutions.
Real-world example
An insurance company uses AutoML to build a fraud detection system within hours instead of manually testing dozens of algorithms.
Common mistakes
- Blindly trusting leaderboard metrics, ignoring explainability, using poor-quality datasets, and deploying AutoML models without validation.
Follow-up questions
- Can AutoML perform feature engineering?
- What metrics can AutoML optimize?
- Is AutoML suitable for production?
