`load_digits()`函数是scikit-learn库中的一部分,用于加载手写数字数据集。该数据集包含了一系列的手写数字图片,每张图片的尺寸为8x8像素。可以通过以下代码来加载数据集: fromsklearn.datasetsimportload_digits digits=load_digits() 数据集的结构 加载数据集后,我们可以通过以下代码来查看数据的结构: print(digits....
load_digits的descr函数 load_digits函数从sklearn.datasets中加载digits数据集,该数据集包含1797张手写数字的图片,每张图片8像素宽和8像素高,共64个像素。每个数字都已经用0至15的灰度值渲染了。因此,该数据集是一个流行的图像分类问题,因为我们需要学习如何将具有64个输入特征的图像映射到数字0至9的输出类别中。
1.手写数字数据集 from sklearn.datasets import load_digits digits = load_digits() 2.图片数据预处理 x:归一化MinMaxScaler() y:独热编码OneHotEncoder()或to_categorical 训练集测试集划分 张量结构 3.设计卷积神经网络结构 绘制模型结构图,并说明设计依据。 先导入相关的包 然后设计模型结构,因为图片是(8,8...
