摘要:

本文提出了一种用于无线网络流量预测(NTP)模型的基于元学习的超参数优化新框架。主要目标是积累并利用所获得的超参数优化经验,从而能够快速确定新任务的最优超参数。本文采用基于注意力的深度神经网络(ADNN)作为基础学习器来解决特定的NTP任务。元学习器是一个融合了元学习与k近邻算法(KNN)、遗传算法(GA)和门控残差网络(GRN)的创新框架。具体而言,KNN用于为新任务识别一组候选超参数选择策略,随后将其作为GA的初始种群,而基于GRN的染色体筛选模块加速了子代染色体的验证,最终确定最优超参数。实验结果表明,与贝叶斯优化(BO)、GA和粒子群优化(PSO)等传统方法相比,所提出的框架能更快速地确定最优超参数,显著减少了优化时间,并提升了基础学习器的性能。它在优化效率与预测精度之间实现了最佳平衡。

英文摘要:

This paper proposes a novel meta-learning based hyper-parameter optimization framework for wireless network traffic prediction (NTP) models. The primary objective is to accumulate and leverage the acquired hyper-parameter optimization experience, enabling the rapid determination of optimal hyper-parameters for new tasks. In this paper, an attention-based deep neural network (ADNN) is employed as the base-learner to address specific NTP tasks. The meta-learner is an innovative framework that integrates meta-learning with the k-nearest neighbor algorithm (KNN), genetic algorithm (GA), and gated residual network (GRN). Specifically, KNN is utilized to identify a set of candidate hyper-parameter selection strategies for a new task, which then serves as the initial population for GA, while a GRN-based chromosome screening module accelerates the validation of offspring chromosomes, ultimately determining the optimal hyper-parameters. Experimental results demonstrate that, compared to traditional methods such as Bayesian optimization (BO), GA, and particle swarm optimization (PSO), the proposed framework determines optimal hyper-parameters more rapidly, significantly reduces optimization time, and enhances the performance of the base-learner. It achieves an optimal balance between optimization efficiency and prediction accuracy.
