arXiv:2606.04866v1 Announce Type: new Abstract: Large-scale hyperparameter optimization (HPO) in automated machine learning (AutoML) consumes substantial computational resources, raising growing concerns about scalability and energy efficiency. Existing methods use prior information heuristically to accelerate both black-box and multi-fidelity settings, but they lack a characterization of how prior informativeness quantitatively reduces sample complexity. In this work, we provide the first distribution-dependent sample complexity bounds for multi-fidelity HPO with priors through the formal len
The increasing scale and computational demands of AI development necessitate more efficient optimization methods, making resource reduction a critical research area.
Reducing the sample cost in hyperparameter optimization directly addresses the compute and energy efficiency concerns that are becoming significant bottlenecks for large-scale AI.
This research provides a formal framework and quantitative bounds for how prior information can reduce the sample complexity of multi-fidelity HPO, moving from heuristic to provable efficiency gains.
