Although the properties of space line method in face recognition once won a huge victory, however research notes face image very likely is spread in an embedded to the high dimensional image space to lower dimensional non linear manifold nature, and face recognition is often high-dimensional small sample performance, in the small sample set exercises the subspace classifier consequences are not very good. This paper studies the basic manifold, manifold learning of non parametric kernel dimensionality reduction methods, semi supervised Manifold Regularization classification method to stop deep discussion. In this paper, an important stop the following research work: (1) research based on nonparametric regression dimensionality reduction method of nuclear spectrum through of manifold learning coherent theory and techniques in the feature extraction of research, for expanding the graph embedding nuclear way of kernel function selection and structure affects function approach, and manifold learning dimension reduction usually need to touch the computing time and space complexity high dense matrix differentiation characteristics of achievement. The based on manifold learning graph embedding dimensionality reduction framework, the introduction of non parametric kernel learning and spectral regression method, is proposed based on non parameter nuclear spectrum regression of dimensionality reduction methods, effectively prevented the specific results the choice of kernel function and structure difficult, with efficiency and scalability. (2) the research based on the semi supervised Manifold Regularization speed of machine learning approach for based on nuclear semi supervised learning methods with high computing complexity, combined with Manifold Regularization and pairwise constraint information, and learn fast to the speed of machine learning approach proposed a new semi supervised manifold regularized extreme learning machine algorithm based on supply the traditional semi supervised approach, an approximate method, not only practical to semi supervised and practical situation for the decision function to study obligations of large-scale, in real data sets of test results verify the algorithm proposed in this paper is useful. (3) designed and completed a manifold learning based face identification prototype system by improving their face identification in the process of face data descending dimension method and face identification classification method, designed and completed the prototype system based on the non parametric spectrum kernel regression algorithm for dimensionality reduction and semi supervised Manifold Regularization extreme learning machine, using the ORL and yale face database as data completed the design of software system.目录:致谢4-5摘要5-6Abstract6-7目录8-10Contents10-12图清单12-14表清单14-151 绪论15-21&&&&1.1 人脸识别背景与意义15-16&&&&1.2 人脸识别的研究现状16-18&&&&1.3 本文的主要研究内容18-19&&&&1.4 本文结构及章节安排19-212 相关理论与技术21-31&&&&2.1 引言21&&&&2.2 流形学习21-23&&&&2.3 几种代表性的流形学习算法23-27&&&&2.4 极速学习机27-30&&&&2.5 本章小结30-313 基于非参数核谱回归的降维算法31-42&&&&3.1 引言31&&&&3.2 图嵌入降维算法31-33&&&&3.3 非参数核学习算法33-35&&&&3.4 基于非参数核谱回归的降维算法35-38&&&&3.5 实验结果与分析38-40&&&&3.6 本章小结40-424 基于半监督流形正则化的极速学习机算法42-54&&&&4.1 引言42&&&&4.2 半监督学习42-46&&&&4.3 流形假设和成对约束信息46-47&&&&4.4 基于半监督流形正则化的极速学习机算法47-49&&&&4.5 实验结果与分析49-53&&&&4.6 本章小结53-545 原型系统设计与实现54-60&&&&5.1 引言54&&&&5.2 系统设计与实现54-57&&&&5.3 系统功能演示57-59&&&&5.4 本章小结59-606 总结与展望60-63&&&&6.1 本文总结60&&&&6.2 进一步的研究工作60-63参考文献63-67作者简历67-69学位论文数据集69分享到:相关文献|
