Multi-objective cloud workflow scheduling algorithm based on grid variance by Xiaoan BAO, Yundi CAO, Na ZHANG, Junyan QIAN, Jianwen CAO

“…Multi-objective cloud workflow scheduling algorithm based on grid variance and the strategy of bad particles self-learning were presented.Firstly,the characteristics of task scheduling was token into consideration,and particle encoding was discredited.Secondly,the strategy of mapping Pareto optimal workflow scheduling set to self-adaptive grid coordinate system,and calculating the grid distribution value of each Pareto optimal solution was used.Thirdly,grid variance was adopted to evaluate the diversity of current Pareto front and dynamically adjust evolution strategies.Finally,the concept of being dominated times was introduced into bad particles self-learning strategy for filtering out bad particles in population.The simulation experiment shows that workflow scheduling solution set by this algorithm is better than the MOPSO algorithm on both IGD and S performance indexes,and the optimal value is superior to the ε-FDPSO and NSGA-Ⅱ algorithm.…”

Privacy matching-based service proxy discovery scheme by Kui GENG, Sheng WAN, Feng-hua LI, Yuan-yuan HE, Han-yi WANG

“…According to user's requirements on the proxy performance,cost and safety in proxy discovery,and the pri-vacy-preserving issue during the process of the demand private matching,a new private matching algorithm was pre-sented based on Paillier homomorphic encryption,comprehensively considered the attributes of user and agents and their priority.It included four steps:building the similarity function based on Euclidean distance,carrying on the private matching by encryption algorithm,calculating the similarity and screening the proxy chain.Proposed scheme introduced semi trusted primary proxy from the global level,which is to manage all the sub proxy's business type and the connection status,and do the main computational overhead.At the same time,Euclidean distance and Paillier homomorphic encryp-tion algorithm were combined to support the multivariate attributes with priority to match,which can effectively protect the privacy of user and sub proxy.Finally,security analysis and evaluation results show the effectiveness and safety of proposed scheme.…”

Noise robust chi-square generative adversarial network by Hongjun LI, Chaobo LI, Shibing ZHANG

“…Aiming at the obvious difference of image quality generated by generative adversarial network under different noises,a chi-square generative adversarial network (CSGAN) was proposed.Combing the advantages of quantification sensitivity and sparse invariance,the chi-square divergence was introduced to calculate the distance between the generated samples and the original samples,which could reduce the influence of different noises on the generated samples and the quality requirement of original samples.Meanwhile,the network architecture was built and the global optimization objective function was constructed to enhance the adversarial performance.Experimental results show that the quality of the images generated by the proposed algorithm has little difference,and the network is more robust to different noises than the state-of-the-art networks.The application of chi-square divergence not only improves the quality of generated images,but also increases the robustness of the network under different noises.…”
