Overfitting and Underfitting: When a Model Memorizes Too Much or Learns Too Little

📰 Medium · Machine Learning

Learn to identify overfitting and underfitting in machine learning models and why it matters for accurate predictions

intermediate Published 3 Jul 2026
Action Steps
  1. Split your data into training, validation, and test sets to evaluate model performance
  2. Monitor validation metrics to detect overfitting or underfitting
  3. Apply regularization techniques to prevent overfitting
  4. Adjust model complexity to avoid underfitting
  5. Compare model performance on validation and test sets to ensure generalization
Who Needs to Know This

Data scientists and machine learning engineers can benefit from understanding overfitting and underfitting to improve model performance and generalization

Key Insight

💡 Overfitting occurs when a model memorizes the training data, while underfitting happens when a model is too simple to learn from the data
