Aiming at the characters of soft sensor modeling,a new soft sensor method based on AbaBoost.R2 and ELM is proposed in this paper.AdaBoost.R2 can improve the accuracy of single learner,and ELM has the character of learning extremely fast.According these characters AdaBoost.R2 and ELM are combined in this new method.Therefore,the new soft sensor method not only can improved the accuracy but also insure that the model can learn fast.The new soft sensor method is used to predict the rock burst in Fushun Laohuta...
