说明：  巴西电商数据集，含九张分类表，可用于电子商务数据统计分析。(Brazilian e-commerce data set, including nine classifications, can be used for statistical analysis of e-commerce data.)

说明：  2DPCA是一个图像特征提取的算法。本代码中使用的分类器是最近邻分类器，最后得到的是一个图片识别率与特征矩阵维数的散点图，符合论文《Two-Dimensional PCA: A New Approach to Appearance-BasedFace Representation and Recognition》的预期结果。(2DPCA is an algorithm for image feature extraction. The classifier used in this code is nearest neighbor classifier, and the final result is a scatter diagram of image recognition rate and feature matrix dimensions, which conforms to the expected results of "Two-dimensional PCA: A New Approach to Appearance-BasedFace Representation and Recognition".)
