Learn how to use cross-validation to improve your machine learning model's performance and avoid overfitting

intermediate Published 28 Apr 2026
Action Steps
  1. Apply cross-validation to your dataset to evaluate your model's performance
  2. Split your data into training and testing sets using a suitable method such as k-fold cross-validation
  3. Use metrics such as accuracy, precision, and recall to evaluate your model's performance on the testing set
  4. Compare the performance of your model on different subsets of the data to identify potential biases
  5. Configure your model to use techniques such as regularization to prevent overfitting
