UDP算法是一种基于流形学习的无监督降维算法，可以用来提取特征和可视化分析。(UDP algorithm is an unsupervised dimensionality reduction algorithm based on manifold learning, which can be used to extract features and visual analysis.)

小说类爬虫的集合，这类网页的特征是需要提取的文本特别多， 特别是中文，解析却相对简单，涉及的js较少 **思路**：爬目录页，解析各章节链接，爬各章节，解析，保存到txt里 大部分的小说当然不是自己看啦，主要拿来练习爬虫和做文本分析用(Novel collection of reptiles, the characteristics of such pages is the need to extract the text in particular, Especially in Chi

实现人脸特征定位及人脸描述符提取功能。很好很强大。(To get started, run "demo". This detects faces in the example image, loading cached detections from files if available, localizes the facial features and extracts descr iptors for each face.)

连 续 投 影 算 法(SPA)是 一 种 使 矢 量 空 间 共 线 性最小化的前向变量选择算法， 它的优势在于提取全波段的几个特征波长， 能够消除原始光谱矩阵中冗余的信息，可用于光谱特征波长的筛选(Continuous projection to calculate method (SPA) is a kind of minimizing vector spatial collinear prior to variable selection algorithm, and it has th
