| Abstract(in English) | In this investigation, we propose a new classification method based on transfer learning to classify new classes without training data of that class. Generally,features of classes is obtained from labelled data. However, large amount of labeled data is required to obtain features of classes . Transfer learning utilizes extracted knowledge from source domain to analyze the target domain. We extract latent topics based on topic model from source domain. And we select appropriate source domain corresponding to class of target domain using features of class tag. We estimate a class of document in target domain by class information of source domain. |
