Automated Modeling Method for Pathloss Model Discovery

  • 用深度符号回归和柯尔莫哥洛夫网络自动构建传播模型。
  • 在真实数据上实现近1的决定系数,预测误差降低75%。
  • 适合通信系统设计者快速获取可解释的传播模型。

无线传播建模是下一代无线系统设计与优化的基础,尤其在5G及以后时代尤为重要。传统方法依赖统计技术刻画不同环境下的传播特性,但随着通信系统扩展,对建模精度与可解释性的要求日益提高。人工智能(AI)技术被越来越多地用于解决该问题,但多数方法缺乏可解释性。受近期AI进展启发,本文提出一种新方法,加速路径损耗模型的发现并保持可解释性。该方法自动化地完成模型构造、评估与优化。我们对比了两种技术:基于深度符号回归的方法具备完全可解释性,而基于柯尔莫哥洛夫-阿诺德网络的方法提供双层级可解释性。两者在两个合成数据集和两个真实世界数据集上进行了评估。结果表明,柯尔莫哥洛夫-阿诺德网络实现了接近1的决定系数(R²),预测误差极小;深度符号回归生成了紧凑模型,准确率中等。此外,在选定案例中,自动化方法相比传统方法预测误差降低高达75%,提供了准确且可解释的解决方案,有望显著提升下一代路径损耗模型的发现效率。

原文摘要 · Abstract (English)

Modeling propagation is the cornerstone for designing and optimizing next-generation wireless systems, with a particular emphasis on 5G and beyond era. Traditional modeling methods have long relied on statistic-based techniques to characterize propagation behavior across different environments. With the expansion of wireless communication systems, there is a growing demand for methods that guarantee the accuracy and interpretability of modeling. Artificial intelligence (AI)-based techniques, in particular, are increasingly being adopted to overcome this challenge, although the interpretability is not assured with most of these methods. Inspired by recent advancements in AI, this paper proposes a novel approach that accelerates the discovery of path loss models while maintaining interpretability. The proposed method automates the formulation, evaluation, and refinement of the model, facilitating the discovery of the model. We examine two techniques: one based on Deep Symbolic Regression, offering full interpretability, and the second based on Kolmogorov-Arnold Networks, providing two levels of interpretability. Both approaches are evaluated on two synthetic and two real-world datasets. Our results show that Kolmogorov-Arnold Networks achieve the coefficient of determination value R^2 close to 1 with minimal prediction error, while Deep Symbolic Regression generates compact models with moderate accuracy. Moreover, on the selected examples, we demonstrate that automated methods outperform traditional methods, achieving up to 75% reduction in prediction errors, offering accurate and explainable solutions with potential to increase the efficiency of discovering next-generation path loss models.
