weighted bits of MSB. MSB is at the leftmost of the binary, and MSB first is at the top of the most effective bit. Magic number writes the ELF header file constant in the ELF Format (Executable and Linkable Format), checks whether the file is consistent with your own settings, and determines whether the file is damaged. Training set image file train-images-idx3-ubyte formats: magic number, number of images, number of rows, number of columns, pixel.The value range of pixel (pixels) is 0-255, and

TensorFlow Study Note Five: mnist example-convolutional neural Network (CNN)

The mnist examples of convolutional neural networks and the neural network examples in the previous blog post are mostly the same. But CNN has more layers, and the network model needs to be built on its own.The procedure is more complicated, I will be divided into several parts to describe.First, download and load the data:Importimport= Input_data.read_data_sets

In batches of multiple calculations, the loop should be used, and the data is divided into batches (batch), the method is built in batches: Batch = Mnist.train.next_batch (100) When running, you must feed into batch input as follows: For _ in range: batch = Mnist.train.next_batch ( train_step.run) (Feed_dict={x:batch
