Study of the ternary correlation quantum-behaved PSO algorithm
Published 2015-03-01“…In order to more effectively utilize existing information and improve QPSO's (quantum-behaved particle swarm optimization) convergence performance, the ternary correlation QPSO (TC-QPSO) algorithm was proposed based on the analysis of the random factors in location formula. The novel algorithm changed the information independent ran-dom processing method of standard QPSO and established internal relations during particles' own experience information, group sharing information and the distance from the particles' current location to the population mean best position using normal copula functions.Then, the method of generating ternary correlation factors was given by using the Cholesky square root formula. …”

Impact of the nationwide implementation of mobile number portabilityon mobile communications market
Published 2019-09-01“…China’s mobile users were taken as a research object,using the random sampling survey method and the survey way of CATI (computer-assisted telephone interviewing) to conduct research on the mobile subscribers market’s structure and impact after implementation of MNP (mobile number portability).The Markov probability transfer matrix was used to predict the market share of mobile phones in China,North China and South China after the implementation of MNP.And the inflow and outflow path model was proposed innovatively.In addition,the focus was on regional characteristics,duration of use,ARPU value and number of MNP to further analyze the concerns and reasons of MNP.The result shows that the longer duration of use,the higher the ARPU value,and the stronger the willingness to choose other operators and the northern subscribers have more willing than the southern.The conclusions provide reference for the decision-making of communication operators.…”

An orchestration algorithm of 5G network slicing
Published 2017-08-01“…The network slicing is an important technology for 5G to implement the on-demand networking based on SDN/NFV network architecture.According to the main scene of 5G,a network segmentation algorithm based on GA-PSO was proposed in SDN/NFV architecture.The merit of quick converging to the global optimal solution was used to design the evaluation function of the network slicing.Using the ability of the fast random search of genetic algorithm,the updating and optimization of the network slices could be realized by using the particle swarm to chase the local optimal solution and the global optimal solution.The simulation results show that the algorithm can realize the personalized creation of multi-service scene network slices,and give full play to the advantages of SDN centralized control mode.It can reduce the energy consumption of the network and improve the utilization rate of cyber source at the same time.…”

Research on security architecture of strong PUF by adversarial learning
Published 2021-06-01“…To overcome the vulnerability of strong physical unclonable function, the adversarial learning model of strong PUF was presented based on the adversarial learning theory, then the training process of gradient descent algorithm was analyzed under the framework of the model, the potential relationship between the delay vector weight and the prediction accuracy was clarified, and an adversarial sample generation strategy was designed based on the delay vector weight.Compared with traditional strategies, the prediction accuracy of logistic regression under new strategy was reduced by 5.4% ~ 9.5%, down to 51.4%.The physical structure with low overhead was designed corresponding to the new strategy, which then strengthened by symmetrical design and complex strategy to form a new PUF architecture called ALPUF.ALPUF not only decrease the prediction accuracy of machine learning to the level of random prediction, but also resist hybrid attack and brute force attack.Compared with other PUF security structures, ALPUF has advantages in overhead and security.…”
