In the practice of designing neural network ensembles, it is common that a certain learning error function is defined and kept the same or fixed for each individual neural network in the whole learning process. Such fixed learning error function not only likely leads to over-fitting, but also makes learning slow on hard-learned data points in the data set. This paper presents a novel balanced ensemble learning approach that could make learning fast and robust. The idea of balanced ensemble learning is to define adaptive learning error functions for different individual neural networks in an ensemble, in which different individuals could have different formats of error functions in the learning process, and these error functions could be changed as well. Through shifting away from well-learned data and focusing on not-yet-learned data by changing error functions for each individual among the ensemble, a good balanced learning could be achieved for the learned ensemble.
