A better understanding of overtuning will help the #AutoML community design more reliable optimization and selection strategies, especially in small-data regimes where robustness is critical. 🚀

Our large-scale analysis shows overtuning is more common than we expected, occasionally severe, and influenced by factors like resampling strategy, dataset size, and model class.

We formally define and study overtuning, a phenomenon where hyperparameter optimization improves validation scores but hurts true generalization. In addition, we relate it to (meta-)overfitting and put recent literature in perspective.

Very proud our paper "OpenML: Insights from 10 years and more than a thousand papers" that describes the current state of OpenML and also analyzes the impact OpenML had over the last years (yes, we manually looked at every paper citing OpenML). #openml #automl #openscience 1/4
