Underdetermined mixing matrix estimation algorithm based on tensor analysis by Baoze MA, Guojun LI, Cuiling XIANG, Yang XU

“…Aiming at the problems of difficult to extract effective feature information and the slow convergence speed of the underdetermined matrix estimation, an underdetermined matrix estimation algorithm of instantaneous mixtures based on tensor analysis was proposed to overcome the constraint of signal sparsity.In the proposed algorithm, the symmetric third-order tensor was constructed via the autocovariance matrix of segmentation sub-block, which was compressed into a kernel tensor to reduce the size of the data.An enhanced line search technology was applied to speed up the convergence of alternating least squares method, and the factor matrix was used as the measure of the mixing matrix estimation, but the selection of the number of segmentation sub-blocks was an open problem.Experimental results demonstrate that the proposed algorithm outperforms the sparse transformation method and the traditional high-order statistical method in handling the underdetermined mixing matrix estimation.…”

Parallel division clustering algorithm based on Spark framework and ASPSO by Yimin MAO, Dejin GAN, Liefa LIAO, Zhigang CHEN

“…To deal with the problems that the partition clustering algorithm for processing massive data encountered problems such as large data dispersion coefficient and poor anti-interference, difficulty to determine the number of local clusters, local cluster centroids randomness, and low efficiency of local cluster parallelization and merging, a parallel partition clustering algorithm based on Spark framework and ASPSO (PDC-SFAS PSO) was proposed.Firstly, a meshing strategy was introduced to reduce the data dispersion coefficient of the data division and improve anti-interference.Secondly, to determine the number of clusters, meshing strategy based on potential function and Gaussian function were proposed, which formed an area with different sample points as the core clusters, and obtained the number of local clusters.Then, to avoid local cluster centroids randomness, ASPSO was proposed.Finally, a local cluster merging strategy based on cluster radius and neighbor nodes was introduced to merge clusters with large similarity based on the Spark parallel computing framework, which improved the efficiency of parallel merging of local clusters.Experimental results showed that the PDC-SFASPSO algorithm has good performance in data partitioning and clustering in a big data environment, and it was suitable for parallel clustering of large-scale data sets.…”

Active queue management algorithm focusing on fairness and low delay by Cheng-long SU, Guang JIN, Xian-liang JIANG, Jun NIU

“…The popularity of delay sensitive applications and high throughput applications in the Internet made the caches of routers and switches larger,resulting in the high latency and high jitter rate of network traffic.With the growth of mobile applications based on the high bandwidth non-response flows,the network bottleneck resource utilization becomes more unbalanced,and the resources distribution of the whole network was difficult to be guaranteed.In order to alleviate these problems,considering the delay control and suppression of high bandwidth non-response flow,an active queue management algorithm focusing on fairness and low delay named FLDA was proposed based on Sample-Match,L-LRU cache and probabilistic packets dropping.Experimental results show that under the interference with high bandwidth non-responsive flows,FLDA can better maintain the queue stability,the fairness of resource utilization of the bottleneck link and the low delay.…”
