MATLAB_SMOTE

计算传递熵延迟时间的程序，根据延迟对应最大传递熵的原理(A program for calculating the delay time of transfer entropy)

数据挖掘，推荐系统，堆叠降噪自编码器，逻辑回归(Data mining, recommender systems, stack noise reduction, self coder, logic regression)

通过Python对妹子图网站的图片集进行爬取(Crawling the collection of images on the sister map site via Python)

该程序用于分类，用到的算法是Bagging and Knn 两种算法(This program is used for classification, the algorithm used is bagging and knn two algorithms)

说明：  从数据库获取车辆在一段时间内的所有行驶记录的相关数据，确定所需数据为GPS经纬度坐标和驾驶时长等，QB模型采用MDF的思想,其基本思想为:通过平均直接翻转距离函数定义两条轨迹之间的距离，两条轨迹需要具有相同的经纬度点数，具有相同点数的轨迹最大的优点是对轨迹距离成对计算，且相同轨迹之间具有更高的分辨率，对于轨迹聚类的结果有一定的优化。(Retrieved from the database cars all over a period of time, record the related data, determine the required data for the GPS latitude and longitude coordinates, and the driving time, QB model by adopting the idea of MDF, its basic idea is: flip directly by the average distance function definition of the distance between two trajectories, two tracks will have the same latitude and longitude points, and has the biggest advantages of the same points of trajectory track distance calculation in pairs, and has higher resolution, between the same trajectory for trajectory clustering results have certain optimization.)

google搜索的核心技术,VC++源码实现,包含测试数据库()

Clustering the data with Density-Based Scan Algorithm with Noise (DBSCAN)

用于数据自编码，非线性压缩，降维的一种方法；与PCA不同，pca为线性降维方式(Data auto encoding, nonlinear compression)

通过优化的k-means算法 采用了密度和优化评测函数实现了对Iris等数据集的聚类。 

说明：  聚类评价指标的各种说明，非常详细，请仔细阅读。(Cluster evaluation indicators of various descriptions, very detailed.)
