摘要:

本文提出一种交叉熵优化方法,用于深度神经网络训练中基于随机梯度方法的超参数优化。学习算法的超参数取值通常对模型性能(如收敛速度、泛化性能指标等)有很大影响。在某些情况下,学习算法的超参数可作为学习参数的一部分,但在其他场景中,Adam[5]及其变体等随机优化算法的超参数要么固定为常数,要么随时间以单调方式变化。我们在期望最大化(EM)框架下对所提方法进行了深入分析。所提出的用于学习算法超参数优化的交叉熵优化算法(CEHPO)可同等应用于深度学习中的其他优化问题领域。我们希望所提出的方法能为机器学习及其他领域的优化问题提供不同视角与一些洞见。

英文摘要:

In this paper, we present a cross-entropy optimization method for hyperparameter optimization in stochastic gradient-based approaches to train deep neural networks. The value of a hyperparameter of a learning algorithm often has great impact on the performance of a model such as the convergence speed, the generalization performance metrics, etc. While in some cases the hyperparameters of a learning algorithm can be part of learning parameters, in other scenarios the hyperparameters of a stochastic optimization algorithm such as Adam [5] and its variants are either fixed as a constant or are kept changing in a monotonic way over time. We give an in-depth analysis of the presented method in the framework of expectation maximization (EM). The presented algorithm of cross-entropy optimization for hyperparameter optimization of a learning algorithm (CEHPO) can be equally applicable to other areas of optimization problems in deep learning. We hope that the presented methods can provide different perspectives and offer some insights for optimization problems in different areas of machine learning and beyond.
