Collaborative Construction of Measurement Matrix and Reconstruction Algorithm in Compressive Sensing
摘要：This paper proposes a novel Sensing Dictionary-based Iterative Hard Thresholding (SDIHT) algorithm,which can collaboratively construct the measurement matrix and the reconstruction algorithm in compressive sensing.Pairs of measurement matrix and sensing dictionary are used for compressive projection and designing reconstruction algorithm respectively.The original sparse signal can be recovered exactly until the residual is reduced to zero as iteration proceeds.A sufficient condition for SDIHT algorithm is given and proved.The benefit of SDIHT is its high reconstruction accuracy and low computational complexity.Computer simulation indicates that when the signal sparsity or the measurement number is fixed,SDHIT algorithm can reconstruct 0-1 sparse signal and two dimensional images with better performance and higher efficiency than IHT,OMP and BIHT algorithm can.关键词：compressive sensing;measurement matrix;reconstruction algorithm;sensing dictionary2|3|11更新时间：2025-07-16 - 摘要：Tri-Training algorithm in semi-supervised learning broke the restriction of previous algorithms on sufficient and redundant views and raised label efficiency by applying three classifiers to deal with labeled confidence.In order to further improve classifiers' performance through enhancing the difference between them,a semi-supervised collaborative classification algorithm with enhanced difference that applies three different classifiers was presented in this paper.Taking the might-be performance deterioration led by random sampling during the updating of classifying models into consideration,a method of stratified sampling based on labeled class was used by the algorithm to sample from the labeled sample sets,and the method of weighted voting based on classification accuracy realized the classifier ensemble,as a result the prediction accuracy is raised.Performance comparison between the proposed algorithm and Tri-Training algorithm was made through experiments,and the results show effectiveness of the former.关键词：semi-supervised collaboration classification algorithm;Tri-Training algorithm;strategy of enhancing difference;stratified sampling2|3|3更新时间：2025-07-16
