| Abstract(in English) | Unlabeled data are used to improve the accuracy of classifiers when the number of labeled data is not enough. In probabilistic approach, the ratio of the numbers of labeled and unlabeled data used for training affects the accuracy of the classifiers, and therefore the ratio should be adjusted to effectively use the unlabeled data. We propose a new method for determining the optimal ratio based on maximum entropy principle. Through text classification experiments using three sets of real data, we have confirmed the usefulness of the proposed method. |
