- Abstract:
-
Diversity among classifier models has been recognized as a significant performance index of a classifier ensemble. Currently, most diversity measuring methods are defined based on the 0/1 outputs (namely Oracle outputs) of the base model. The probability vector outputs of a convolutional neural network (CNN) still need to be converted into Oracle outputs for measurement, which fails to fully use the rich information contained in the CNN probability vector outputs. To solve this problem, a new diversity measuring method for probabilistic vector outputs based on CNNs is proposed. Several base models of CNN models with various structures are established and tested on the CIFAR-10 and CIFAR-100 datasets. Compared with double-fault measure, disagreement measure, and Q-Statistic, the proposed method can better reflect the differences between the models and provide better guidance for a selective ensemble of CNN models.
