股票收益预测的超参数优化

Hyperparameter Optimization for Forecasting Stock Returns

Sang Il Lee

摘要:

近年来,超参数优化(hyperparameter optimization,HPO)已成为机器学习领域中越来越重要的问题,以开发更精确的预测模型。在这项研究中,我们探索了HPO在使用深度神经网络(DNN)建模股票收益方面的潜力。这种方法的潜力进行了评估,使用技术指标和基本检查的基础上的效果,辍学和批量正常化的所有输入数据。我们发现,使用技术指标和辍学正则化的模型显著优于其他三个模型,显示出0.53%的样本内和1.11%的样本外的正预测性,从而表明有可能击败历史平均水平。我们还证明了模型的稳定性,其特征重要性随时间的变化。

英文摘要:

In recent years, hyperparameter optimization (HPO) has become an increasingly important issue in the field of machine learning for the development of more accurate forecasting models. In this study, we explore the potential of HPO in modeling stock returns using a deep neural network (DNN). The potential of this approach was evaluated using technical indicators and fundamentals examined based on the effect the regularization of dropouts and batch normalization for all input data. We found that the model using technical indicators and dropout regularization significantly outperforms three other models, showing a positive predictability of 0.53% in-sample and 1.11% out-of-sample, thereby indicating the possibility of beating the historical average. We also demonstrate the stability of the model in terms of the changes in its feature importance over time.
