Cell Scene Division and Visualization Based on Autoencoder and K-Means Algorithm
TL;DR: This paper trains an autoencoder network to conduct the dimension reduction of the wireless perception key quality indicator (KQI) data of cells, and uses elbow method and K-means algorithm to cluster the dimension-reduced data precisely and achieves accurate cell scene division and visualization.
Journal ArticleDOI
Semi-Supervised Machine Learning Aided Anomaly Detection Method in Cellular Networks
TL;DR: This paper proposes a KQIs-based QoE anomaly detection framework using semi-supervised machine learning algorithm, i.e., iterative positive sample aided one-class support vector machine (IPS-OCSVM) and proves that the fluctuation of KQ is thresholds based on expert knowledge has a limited impact on the result of anomaly detection.
Journal ArticleDOI
Machine Learning Based Quantitative Association Rule Mining Method for Evaluating Cellular Network Performance
TL;DR: A machine learning based quantitative association rule mining (QARM) method called SWP-RF, which consists of sliding-window partitioning (SWP) and random forest (RF), to associate KPI with KQI, is proposed.
Journal ArticleDOI
WeUp: Wireless User Perception Based on Dimensional Reduction and Semi-Supervised Clustering
TL;DR: The study indicates that dimensional reduction and semi-supervised machine learning method is effective in recognizing unsatisfied WeUP in wireless networks.
Proceedings ArticleDOI
Cellular Network Performance using Machine Learning based Quantitative Association Rule Mining Method
TL;DR: This work proposes a machine learning-based quantitative association rule mining (QARM) method called SWP to associate KPI with KQI, which mainly discretizes continuous attributes into boolean values and the association rules of these boolean values are mined by QARM algorithms, such as the Apriori algorithm.
