新的高斯-牛顿方法优化AI模型超参数

研究人员开发了一种基于阻尼高斯-牛顿方法的新型多目标超参数优化方法。该技术将超参数调整视为一个数值优化问题,估计雅可比矩阵以了解多个验证指标对超参数变化的敏感性。该方法在XGBoost分类任务的超参数上进行了测试,结果与网格搜索、随机搜索和TPE相比具有竞争力,特别是在乳腺癌数据集上,其准确率与网格搜索相当,同时改善了log loss和ROC-AUC。 AI

影响 这项研究为超参数调整提供了一种新的数值优化方法,有望提高模型训练的效率和有效性。

    通过阻尼高斯-牛顿优化进行多目标超参数搜索

    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…
