Why it matters

  • It is important that your model is validated on a sufficient amount of unseen data. If the validation set is too small compared to the training set, it may not adequately represent the variety of data the model will encounter in the real world, leading to overfitting.
  • The size ratio can also helps ensure the statistical significance of the validation results.
