压缩感知中利用增广拉格朗日方程解最小稀疏正则化的恢复算法 DAL
压缩感知中利用增广拉格朗日方程解最小稀疏正则化的恢复算法(DAL solves the dual problem of (1) via the augmented Lagrangian method (see Bertsekas 82). It uses the analytic expression (and its derivatives) of the following soft-thresholding operation,
which can be computed for L1 and grouped L1 (and many other) sparsity inducing regularizers. If you are interested in our algorithm please find more details in our technical report or in my talk at Optimization for Machine Learning Workshop (NIPS 2009).)

Harris2
说明: Harris角点检测,关于角点的应用在图像处理上比较广泛,如图像匹配(FPM特征点匹配)、相机标定等。网上也有很多博客对Harris角点检测原理进行描述,但基本上只是描述了算法流程,而其中相关细节并未作出解释,这里我想对有些地方做出补充说明,正所谓知其然知其所以然,如有不对,还望指正。(Harris corner detection)

特征选择之relief-F的MATLAB实现
Relief-F 算法是由 Kononenko 在 Relief 算法基础上扩展得到的,可以用来解决多分类与回归问题。 Relief-F 特征选择算法利用特征与类别间的相关程度判别特征的敏感程度,敏感的特征能使同类样本靠近,非同类样本远离。基本思想是: 先随机从总样本集 D中获取一个样本 R, 然后在 与 R 同类样本集中和与R 异类 样 本 集 中 各 获 取 k 个近 邻 样 本, 在 特 征 集 F中如果某个特征上异类样本的距离大于同类样本,则这个特征是有利于分类的,增加其权重,重复 n 次 取所有结果的均值作为每个特征的最终权重值.
