RMSE-ELM: Recursive Model Based Selective Ensemble of Extreme Learning Machines for Robustness Improvement
Given: training set , (the size of ensemble groups in the first layer), (the size | of each ensemble in the first layer), (the size of candidates pool in the second | layer), is defined in (7), threshold is a pre-set value (reciprocal value of or ). | Steps: | (1) for | { ; | for | { Training each ELM network; | Generating a population of weight vector; | Using selective ensample to get the best weight vector ; | Removing base ELMs that the weights less than ; | } | Calculating the whole remained ELMs of group are ; | ; | } | (2) Training remained ELM; | (3) Using selective ensemble to get the best weight vector ; | (4) Removing base ELMs that the weights less than ; | (5) Getting the final prediction; |
