Semi-supervised Learning from Only Positive and Unlabeled Data Using Entropy
The problem of classification from positive and unlabeled examples attracts much attention currently. However, when the number of unlabeled negative examples is very small, the effectiveness of former work has been decreased. This paper propose an cffective approach to address this problem, and we firstly use entropy to selects the likely pos itive and negative examples to build a complete training set; and then logistic regression classifier is applied on this new training set for classification. A series of experiments are conducted. The experimental results illustrate that the proposed approach outperforms previous work in the literature.
