points of mini project are translated, Then translate the Mini project implementation steps, not a one-time full translation, take too long, the previous translation may forget, and the translation may not be accurate, and sometimes to see the original text. Complete a paragraph and translate the next paragraph, step by step. Do not translate all, some do not help to complete the task can not translate, save time. 4.

Map Reduce and Data Parallelism:
Many learning algorithms can be expressed as computing sums of functions over the training set.
We can divide up batch gradient descent and dispatch the cost function for a subset of the data to many different machines So, we can train our algorithm in parallel.

What are machine learning?The definitions of machine learning is offered. Arthur Samuel described it as: "The field of study that gives computers the ability to learn without being explicitly prog Rammed. " This was an older, informal definition.Tom Mitchell provides a more modern definition: 'a computer program was said to learn from experience E with R Espect to some class of tasks T and performance measure P, if it performance at tasks in T, as measured By P, improves with experience E."Examp

TensorFlow creates a classifier and tensorflow implements classification.
The examples in this article share the code used to create a classifier in TensorFlow for your reference. The details are as follows:

Convolutional Neural Networks Convolutional Neural Network (CNN) transfers the data of an image to CNN. The original coating is composed of RGB, And then CNN thickened the thickness and the length and width become smaller, each layer is stretched to form a classifier.
There are several important concepts in CNN:

Mnist is an entry-level computer-vision dataset that contains 60,000 training data and 10,000 test data. Each sample is a variety of handwritten digital pictures below:
It also contains the corresponding label for each picture, telling us this is a number. For example, the above four pictures are labeled 5,0,4,1.

1. Overview
As with the old version of TensorFlow, the model needs to be saved, and this preservation is cyclical. Because in many cases the gradient will swing around the local minimum, that is to say, in many cases, the last training model is not necessarily optimal.
2. Save the Model
We can create a location where the checkpoint is saved when we build the model, and we can start by creating a folder with the following command.
You can add paramet
