- python - Show image from MNIST DataSet - Stack Overflow
4 On top of the codes in the tutorial MNIST for ML beginners, you can visualize the image in the mnist dataset: import matplotlib pyplot as plt batch = mnist train next_batch(1) plotData = batch[0] plotData = plotData reshape(28, 28) plt gray() # use this line if you don't want to see it in color plt imshow(plotData) plt show() enter image
- mnist手写体识别如何做到99. 0%以上的测试集准确率? - 知乎
Test Accuracy: 99 54% 然后给你些其他思路,比如改进的可以并不是算法,而是mnist数据集本身,你剔除一些模棱两可的样本,比如一个图片人看着又像4又像9,你把它踢掉,减小模型在边界上的抖动,可能会提高一些。 要么你把你的具体模型share出来看具体case…

- python - Display MNIST image using matplotlib - Stack Overflow
with tf Session() as sess: #access first image first_image = mnist train images[0] first_image = np array(first_image, dtype='uint8') pixels = first_image reshape((28, 28)) plt imshow(pixels, cmap='gray') I a attempt to convert the image to a 28 by 28 numpy array because I know that each image is 28 by 28 pixels However, when I run the code all I get is the following Clearly I am doing
- Correct way of normalizing and scaling the MNIST dataset
Basically the MNIST dataset has images with pixel values in the range [0, 255] People say that in general, it is good to do the following: Scale the data to the [0,1] range Normalize the data to have zero mean and unit standard deviation (data - mean) std Unfortunately, no one ever shows how to do both of these things
- 卷积神经网络初探——LeNet-5的原理与手写数字识别的实现 - 知乎
MNIST手写体数字识别代码实现 基于LeNet-5的原理,我使用了TensorFlow来做了简单实现。 Features: 没有对中间的神经元使用激活函数,仅仅对输出层用了softmax函数,同时增加了dropout来避免过拟合。 使用了tensorflow的常规api和封装好的高层api(tf contrib)实现了两个版本。
