Applying continual learning strategy on random vector functional link neural network based ensemble deep learning by Peng, Liuchang

“…After doing the comparisons and analysis, I found that the Continual Learning strategy has the possibility and indeed can be practically applied to the RVFL network and ed-RVFL network which use the Ridge Regression method to compute the weights. The accuracy after applying a continual learning strategy can reach 84% of the original accuracy and the results generated on edRVFL network are 1.36% better than the results generated on RVFL network.…”

A two-layer portfolio model based on machine learning for productivity prediction of garment industry by Zhou, Yiran

“…Seven independent regression models, including ridge regression model, Bayesian linear regression model, polynomial regression model, SVM regression model, random forest regression model, GBDT regression model and neural network regression model, are used as base learners in the bottom layer while a random forest regression algorithm based generalizer is developed in the top layer, aiming to combine the independent regression models together to form one portfolio model. …”

Horn antenna of constant beam width by Zhang, Xiao

“…This project aims at designing a horn antenna that can work during a wide frequency band and its half power beamwidth (HPBW) is nearly invariable. A double-ridged waveguide modified from the conventional one is designed to achieve the broadband operation. …”
