Handwritten Digits数据集的简介 根据官方对数据集的描述,我们可以知道完整的手写体数字图像分为两个数据集合。其中,训练数据样本3823条,测试数据1797条,图像数据通过8X8的像素矩阵表示,共有64个像素维度。1个目标维度用来标记每个图像样本代表的数字类别。该数据没有缺失的特征值,并且不论是训练还是测试样本.在数字类别...
该数据没有缺失的特征值,并且不论是训练还是测试样本.在数字类别方面都采样得非常平均,是一份非常规整的数据集。 We used preprocessing programs made available by NIST to extract normalized bitmaps of handwritten digits from a preprinted form. From a total of 43 people, 30 contributed to the training ...
