New Gauss-Newton method optimizes hyperparameters for AI models

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel multi-objective hyperparameter optimization method based on a damped Gauss-Newton approach. This technique treats hyperparameter tuning as a numerical optimization problem, estimating a Jacobian to understand the sensitivity of multiple validation metrics to hyperparameter changes. The method was tested on XGBoost hyperparameters for classification tasks, showing competitive results against grid search, random search, and TPE, particularly on a breast cancer dataset where it matched grid search accuracy while improving log loss and ROC-AUC. AI

IMPACT This research offers a new numerical optimization approach for hyperparameter tuning, potentially improving efficiency and effectiveness in model training.

    Multi-Objective Hyperparameter Search via Damped Gauss--Newton Optimization

    arXiv:2401.03580v2 Announce Type: replace-cross Abstract: We study hyperparameter optimization (HPO) from a numerical-optimization perspective and propose a multi-objective, damped Gauss--Newton search method. Rather than treating model evaluations as independent trials, the meth…
