    Information entropy based match field cutting algorithm by Peng-hao SUN, Ju-long LAN, Shao-jun ZHANG, Jun-fei LI

    Published 2017-05-01
    “…With the increasing diversity of network functions,packet classification had a higher demand on the number of match fields and depth of match table,which placed a severe burden on the storage capacity of hardware.To ensure the efficiency of matching process while at the same time improve the usage of storage devices,an information entropy based cutting algorithm on match fields was proposed.By the analysis on the redundancy of match fields and distribution pattern in a rule set,a match field cutting model was proposed.With the mapping of matching process to the process of entropy reduction,the complexity of optimal match field cutting was reduced from NP-hard to linear complexity.Experiment results show that compared to existing schemes,this scheme can need 40% less TCAM storage space,and on the other side,with the growing of table size,the time complexity of this algorithm is also far less than other algorithms.…”

    Published 2018-08-01
    “…With the problem of slow convergence for traditional Sarsa algorithm,an improved heuristic Sarsa algorithm based on value function transfer was proposed.The algorithm combined traditional Sarsa algorithm and value function transfer method,and the algorithm introduced bisimulation metric and used it to measure the similarity between new tasks and historical tasks in which those two tasks had the same state space and action space and speed up the algorithm convergence.In addition,combined with heuristic exploration method,the algorithm introduced Bayesian inference and used variational inference to measure information gain.Finally,using the obtained information gain to build intrinsic reward function model as exploring factors,to speed up the convergence of the algorithm.Applying the proposed algorithm to the traditional Grid World problem,and compared with the traditional Sarsa algorithm,the Q-Learning algorithm,and the VFT-Sarsa algorithm,the IGP-Sarsa algorithm with better convergence performance,the experiment results show that the proposed algorithm has faster convergence speed and better convergence stability.…”

    Anti-interference algorithm of wireless channel for IoT communication by Ling TAN, Yong ZHUANG

    Published 2017-10-01
    “…In IoT communication,the anti-interference of wireless channel is influenced by various factors.Multi-antenna system has significant effect for promoting anti-interference of channel,whose complexity and performance in signal detection need further improvement.The QR decomposition detection algorithm in signal detection of multi-antenna system has low computational complexity,but the algorithm performance is poor.In order to improve the performance of QR decomposition detection algorithm,a QR decomposition algorithm based on ML criterion and decision candidate mechanism was proposed,and the performance of the algorithm was analyzed.The ML criterion was used to estimate the initial level of the detection,and a reliable decision was adopted in the other detection layer.Candidate points were introduced in unreliable case and the optimal candidate were selected from the feedback.The algorithm could significantly improve the system interference,and propagation error were greatly reduced in the decision feedback.The experimental results show that the proposed algorithm can improve the performance of the IoT system effectively with certain complexity.…”

    Published 2023-08-01
    “…To adapt to the scenario characteristics of vertical federated learning (VFL) applications regarding high communication cost, fast model iteration, and decentralized data storage, a generalized adversarial sample generation algorithm named VFL-GASG was proposed.Specifically, an adversarial sample generation framework was constructed for the VFL architecture.A white-box adversarial attack in the VFL was implemented by extending the centralized machine learning adversarial sample generation algorithm with different policies such as L-BFGS, FGSM, and C&W.By introducing deep convolutional generative adversarial network (DCGAN), an adversarial sample generation algorithm named VFL-GASG was designed to address the problem of universality in the generation of adversarial perturbations.Hidden layer vectors were utilized as local prior knowledge to train the adversarial perturbation generation model, and through a series of convolution-deconvolution network layers, finely crafted adversarial perturbations were produced.Experiments show that VFL-GASG can maintain a high attack success while achieving a higher generation efficiency, robustness, and generalization ability than the baseline algorithm, and further verify the impact of relevant settings for adversarial attacks.…”
