Journal ArticleDOI
An Adaptive Ensemble Machine Learning Model for Intrusion Detection
TL;DR: It is proved that the ensemble model effectively improves detection accuracy, and it is found that the quality of data features is an important factor to determine the detection effect.
Journal ArticleDOI
An improved WiFi indoor positioning algorithm by weighted fusion
TL;DR: The experimental results indicate that the proposed improved WiFi indoor positioning algorithm by weighted fusion has higher positioning accuracy than the Euclidean distance based WKNN algorithm and the joint probability algorithm.
Journal ArticleDOI
DEPLEST: A blockchain-based privacy-preserving distributed database toward user behaviors in social networks
TL;DR: The experimental results show that DEPLEST meets the architectural and performance needs and that the consensus protocol outperforms the existing proof of work (PoW) and proof of stake (PoS) methods in this application.
Journal ArticleDOI
Network Security Situation Prediction Based on MR-SVM
TL;DR: A cyber security situation prediction model based on MapReduce and the SVM is proposed that has improved the accuracy and decreased the training time cost compared to the traditional model.
Journal ArticleDOI
Malware classification for the cloud via semi-supervised transfer learning
TL;DR: A novel malware detection model, based on semi-supervised transfer learning (SSTL) for the cloud, that consists of detection, prediction, and transfer components that can do a better job of resolving the privacy concerns of tenants in the public cloud than other similar methods.
