Hyper-parameter Optimization for Wireless Network Traffic Prediction Models with A Novel Meta-Learning Framework
<|reference_start|>Hyper-parameter Optimization for Wireless Network Traffic Prediction Models with A Novel Meta-Learning Framework: In this paper, we propose a novel meta-learning based hyper-parameter optimization framework for wireless network traffic prediction models. An attention-based deep neural network (ADNN) is adopted as the prediction model, i.e., base-learner, for each wireless network traffic prediction task, namely base-task, and a meta-learner is employed to automatically generate the optimal hyper-parameters for a given base-learner according to the corresponding base-task's intrinsic characteristics or properties, i.e., meta-features. Based on our observation from real-world traffic records that base-tasks possessing similar meta-features tend to favour similar hyper-parameters for their base-learners, the meta-learner exploits a K-nearest neighbor (KNN) learning method to obtain a set of candidate hyper-parameter selection strategies for a new base-learner, which are then utilized by an advanced genetic algorithm with intelligent chromosome screening to finally acquire the best hyper-parameter selection strategy. Extensive experiments demonstrate that base-learners in the proposed framework have high potential prediction ability for wireless network traffic prediction task, and the meta-learner can enormously elevate the base-learners' performance by providing them the optimal hyper-parameters.<|reference_end|>
