Abstract(in English) | In this study, we focus on the Alternating Decision Forests (ADF). The ADF introduces the weights which represent the degree of prediction accuracy for the training data. These weights are only used when growing decision trees in the learning phase to improve the predictability for all training data. By using the weights in the prediction phase, it is possible to construct a prediction considering prediction confidence of each decision tree's leaf node. Moreover, by pruning the decision trees, the generalization ability can also be improved. Therefore, we propose the method introducing AIC criterion to prune brunches of the trees and using the weights when predicting the category label of a new input data. Our proposal can be interpreted as the predictive method to weaken the influence of the low confidence outputs and strengthen that of the high reliable outputs. |
