Abstract

This paper introduces an innovative deep learning-based optimization method specifically designed for data derived from stochastic processes. Addressing the prevalent issue of rapid overfitting in real-world scenarios with limited historical data, our approach focuses on denoising optimization. The method effectively balances the simultaneous optimization of latent data representation and target variables, leading to enhanced model performance. We rigorously test our approach using five diverse real-world datasets. Our study is structured into three parts: an ablation study to validate the individual components of our method, a statistical analysis using the Wilcoxon rank-sum test to confirm the superiority of our method against five research hypotheses, and a detailed exploration of parameter visualization and fine-tuning. The comprehensive evaluation demonstrates that our method not only outperforms existing techniques but also significantly contributes to the advancement of deep learning models for stochastic processes. The findings underscore the potential of our method as a robust solution to the challenges in modeling stochastic processes with deep learning, offering new avenues for efficient and accurate predictions.
通过智能去噪和潜在表示优化改进随机模型
本文介绍了一种基于深度学习的创新优化方法,该方法专为随机过程衍生的数据而设计。针对现实世界中历史数据有限的情况下普遍存在的快速过拟合问题,我们的方法侧重于去噪优化。该方法有效地平衡了潜在数据表示和目标变量的同步优化,从而提高了模型性能。我们使用五个不同的真实世界数据集对我们的方法进行了严格测试。我们的研究分为三个部分:消融研究以验证我们方法的各个组成部分;使用 Wilcoxon 秩和检验进行统计分析,以确认我们的方法在五个研究假设中的优越性;以及对参数可视化和微调的详细探讨。综合评估结果表明,我们的方法不仅优于现有技术,而且极大地推动了随机过程深度学习模型的发展。这些发现强调了我们的方法的潜力,它是利用深度学习对随机过程建模所面临挑战的一种稳健的解决方案,为高效、准确的预测提供了新的途径。
