| Abstract(in English) | In case a base station in mobile network malfunction, it is crucial to classify a service degradation event and identify a countermeasure to improve the service quality. However, it is difficult for operators to determine the network performance because the network performance in base station is very different depending on location and time. Classification by machine learning is considered a promising solution to this problem. However classification by machine learning requires large amounts of labeled data, which requires costly human-labor tasks to annotate large amounts of data. In order to address this problem we propose a method based on few-show learning that uses Prototypical Networks to analyze performance KPI data of base stations. Using data set obtained from a production LTE network with thousands of eNodeB data, we demonstrate that the proposed yields high detection performance while reducing the number of labeled data. |
