Abstract
En 中文
In order to improve the efficiency of antenna optimization design, a surrogate model is often used to replace the full-wave electromagnetic simulation software. Broad learning system (BLS) provides an alternative method for deep structure, aiming to overcome the drawback of excessive time-consuming training process, however, usually not with satisfactory accuracy. In order to further improve the performance of the model, master-apprentice (MA) behavior is proposed in this paper, using the current BLS training results as the priori knowledge, which are taken as fixed features to the next BLS hidden layer for further training. Each MA behavior forms a double BLS structure, which is composed of two parts, the models trained before and after are called master BLS (MBLS) and apprentice BLS (ABLS) respectively. These two subsystems together constitute a master-apprentice BLS (MABLS). Two antenna examples, rectangular microstrip antenna (RMSA) and WLAN dual-band monopole antenna (DBMA), and 10 UCI regression datasets are employed to demonstrate the effectiveness of the proposed model.
