摘要:

我们介绍了机器学习领域的超参数搜索问题,并从优化的角度讨论了它的主要挑战。机器学习方法试图构建基于给定数据捕获某些感兴趣元素的模型。大多数常见的学习算法都有一组超参数,必须在训练开始前确定。超参数的选择会显著影响结果模型的性能,但确定好的值可能很复杂;因此,有纪律的,理论上合理的搜索策略是必不可少的。

英文摘要:

We introduce the hyperparameter search problem in the field of machine learning and discuss its main challenges from an optimization perspective. Machine learning methods attempt to build models that capture some element of interest based on given data. Most common learning algorithms feature a set of hyperparameters that must be determined before training commences. The choice of hyperparameters can significantly affect the resulting model's performance, but determining good values can be complex; hence a disciplined, theoretically sound search strategy is essential.
