| Abstract(in English) | Recently, there have been a lot of studies on learning a classifier from a large amount of labeled data collected from crowds. However, the existing methods have a problem that the accuracy of the classifier drastically deteriorates if there are malicious annotators intentionally giving wrong labels. In this paper, to solve this problem, we propose a method of learning a classifier resistant to malicious annotators by introducing degrees of similarity between discriminative models of annotators. Through experiments, we show the effectiveness of our proposed method. |
