Validating Validation Sets

Published:Dec 27, 2025 16:16
1 min read
r/MachineLearning

Analysis

This article discusses a method for validating validation sets, particularly when dealing with small sample sizes. The core idea involves resampling different holdout choices multiple times to create a histogram, allowing users to assess the quality and representativeness of their chosen validation split. This approach aims to address concerns about whether the validation set is effectively flagging overfitting or if it's too perfect, potentially leading to misleading results. The provided GitHub link offers a toy example using MNIST, suggesting the principle's potential for broader application pending rigorous review. This is a valuable exploration for improving the reliability of model evaluation, especially in data-scarce scenarios.
