Abstract(in English) | In an LTE network where traffic is increasing year by year. It is important to quickly find the cause when a failure occurs in the eNodeB base station. Therefore, using the eNodeB log data extracted from the base station, 13 types of base station states are clasified by machine learning, and high accuracy is achieved while a few labeled data that is expensive to create. In this paper, semi-supervised learning is performed by using self-training, which considers unlabeled data with high confidence as label data, and the accuracy is improved from 86.73% to 90.13% compared to normal supervised learning. Also, using two types of methods, Active learning to add labels to data with low confidence, and unlabeled loss function, which is an effective loss function for unlabeled data, Accuracy has improved to 90.96%. The advantage of semi-supervised learning in learning with a few label data was clarified. |
