AutoML comparison flaws revealed: Orcetra's inflated performance exposed

By PulseAugur Editorial · [1 sources] ·

A new paper highlights significant flaws in how automated machine learning (AutoML) systems are compared, particularly under short time budgets. The study reveals that a system called Orcetra appeared to outperform competitors like FLAML and AutoGluon due to protocol defects, including testing on the actual test split and failing to enforce time limits. When these issues were corrected by using a validation split and enforcing external deadlines, Orcetra's performance advantage disappeared, indicating that the initial impressive results were inflated by methodological errors.

    Winning by Peeking: Unenforced Budgets and Test-Set Selection Inflate Short-Budget AutoML Comparisons

    arXiv:2608.07303v1 Announce Type: new Abstract: Comparisons between AutoML systems at short time budgets -- tens of seconds rather than hours -- are common in tool READMEs and workshop papers, and they are easy to get wrong. We report a case study in which a simple AutoML engine,…
