Doubly Wild Refitting: Model-Free Evaluation of High Dimensional Black-Box Predictions under Convex Losses

arXiv — stat.MLTuesday, November 25, 2025 at 5:00:00 AM
  • A new study has introduced an efficient refitting procedure for evaluating excess risk in empirical risk minimization under general convex loss functions. This method utilizes artificially modified pseudo-outcomes to create wild predictors, allowing for the computation of high-probability upper bounds without prior knowledge of the underlying function class complexity.
  • This development is significant as it enhances the ability to assess the performance of black-box machine learning models, particularly in high-dimensional settings, which is crucial for applications in various fields including finance, healthcare, and artificial intelligence.
  • The research aligns with ongoing efforts to improve machine learning methodologies, particularly in addressing challenges such as model interpretability and risk assessment. It reflects a broader trend in the AI community towards developing robust evaluation techniques that can adapt to complex, real-world data scenarios.
