“MLshorts” 51: RMSE Isn’t the Only Metric in Regression

📰 Medium · Data Science

Learn why RMSE isn't the only metric for evaluating regression models and how to choose the right metric for your problem

intermediate Published 10 May 2026
Action Steps
  1. Evaluate your regression model using Mean Absolute Error (MAE) to compare with RMSE
  2. Calculate the Coefficient of Determination (R-squared) to assess model fit
  3. Use Mean Absolute Percentage Error (MAPE) to evaluate model performance on datasets with varying scales
  4. Compare the results of different metrics to choose the most suitable one for your problem
  5. Consider using other metrics such as Mean Squared Logarithmic Error (MSLE) or Huber Loss for specific use cases
Who Needs to Know This

Data scientists and machine learning engineers can benefit from understanding the limitations of RMSE and learning about alternative metrics to improve model evaluation

Key Insight

💡 Different metrics provide unique insights into model performance, and choosing the right one depends on the problem and dataset
