Abstract:The paradigm shift from ''connected things'' to ''connected intelligence'' is anticipated to be made possible by the sixth-generation wireless systems, which typically use millimeter wave beamforming to mitigate the significant propagation loss. However, beamforming design in millimeter wave communications poses many different challenges owing to the large antenna arrays with the limitation of radio frequency chains and analog beamforming architectures. To circumvent this problem, deep learning models have rec… Show more
“…18 Hyperparameter optimization is a common method for improving model performance. [19][20][21] Fernández et al utilized hyperparameter optimization techniques to train neural network models, achieving the bestperforming model in terms of accuracy with a minimal risk of overtting for the classication of spectral data; the model demonstrated an overall accuracy exceeding 80% on an 11-class spectral dataset, highlighting its robust generalization capabilities. 22 For specic tasks, pre-trained models oen fail to achieve optimal performance, necessitating improvements to the model.…”
