5G network slicing function migration mechanism based on particle swarm optimization algorithm by Qiang CHEN, Caixia LIU, Lingshu LI

“…In multi-application scenarios of 5G,data traffic often increases dramatically.Virtual machine resources in network slicing may not meet the normal needs of users.In view of this,a network slicing function migration mechanism aiming at load balancing was proposed.The mechanism simulates the virtual machine into particles based on particle swarm optimization algorithm.In the process of migration,all particles were divided into several subgroups,and particle swarm optimization algorithm was applied within and among groups.According to the historical optimal solution and the current global optimal solution,the particle location was updated,and the best target particles were determined by selecting the smaller particle size of the particle in real time.The mechanism not only improves the convergence speed,but also improves the accuracy of the algorithm.Compared with other migration methods,the results show that the proposed migration mechanism has the advantages of high accuracy and fast convergence.And it can also improve the efficiency of resource utilization,reduce the energy consumption of data center,and has better adaptability.…”

Landslide susceptibility assessment based on machine learning and encoder coupling by ZHANG Mengmeng, LI Shaoda, WANG Xiao, LI Xinyue, DAI Keren

“…Twelve influencing factors were selected to construct the landslide susceptibility evaluation index system， the coefficient of determination （CF） was used to quantify the evaluation index， and noise-reducing auto-encoders （DAEs） and convolutional auto-encoders （CAE） were added to the best-performing model by comparing the logistic regression （LR） and the support vector machine（SVM） models.ResultsThe results showed that compared with the CF-LR model， the CF-SVM model， the precision （P）， F-measure， Kappa coefficient， overall accuracy （OA）， and AUC of the CF-SVM model increased by 31.9%， 1.1%， 17.1%， 8.5%， and 8.6%， respectively， After adding the DAE encoder， the recall （R）， F-measure， Kappa coefficient， and overall accuracy （OA） of the CF-SVM-DAE model increased by 8.1%， 5.8%， 8.1%， and 4%， respectively， compared to the CF-SVM model After adding CAE encoders， the recall （R）， F-measure， Kappa coefficient， and overall accuracy （OA） of the CF-SVM-CAE model increased by 0.4%， 0.2%， 0.2%， and 0.1%， respectively， compared to the CF-SVM model.ConclusionsThe CF-SVM model has higher prediction accuracy among the selected machine learning methods. …”
