【摘要】:從模式分類的角度出發(fā),針對典型相關(guān)分析(canonical correlation analysis,CCA)算法不適應于高層次關(guān)聯(lián)的缺陷,提出了改進算法。將深度學習理論與典型相關(guān)分析算法相結(jié)合,基于深度玻爾茲曼機理論提出了一種半監(jiān)督典型相關(guān)分析算法。通過深度玻爾茲曼機提取出樣本的顯層特征與隱層特征,結(jié)合已標注樣本的監(jiān)督信息,構(gòu)造出最有效的鑒別特征。依據(jù)ORL、Yale和AR人臉數(shù)據(jù)庫進行仿真實驗,實驗結(jié)果表明:本文算法與其他的方法相比,具有更好的識別效果。
[Abstract]:From the point of view of pattern classification, an improved (canonical correlation analysis,CCA (canonical correlation analysis) algorithm is proposed to solve the problem that it is not suitable for high-level association. Based on the deep Boltzmann machine theory, a semi-supervised canonical correlation analysis algorithm is proposed based on the combination of depth learning theory and typical correlation analysis algorithm. The most effective discriminant features are constructed by using depth Boltzmann machine to extract the explicit and hidden layer features of the samples and combine the supervised information of the labeled samples to construct the most effective discriminant features. The simulation results based on ORL,Yale and AR face database show that the proposed algorithm has better recognition performance than other methods.
