Tensorflow creates variables and searches for variables by name. tensorflow Variables
Environment: Ubuntu14.04, tensorflow = 1.4 (bazel source code installation), Anaconda python = 3.6
There are two main methods to declare variables:Tf. VariableAndTf. get_variable, The biggest difference between the two is:
(1) tf. Variable is a class with many attribute function
Use tensorflow to implement the elastic network regression algorithm and tensorflow Algorithm

TensorFlow is used for simple linear regression and gradient descent examples. tensorflow gradient
Linear regression is supervised learning. Therefore, the method and supervised learning should be the same. First, a training set is given and a linear function is learned based on the training set, then, test whether the function is trained (that is, whether the function is sufficient to fit the training set

November 9, 2015 Google Open source of the artificial intelligence platform TensorFlow, but also become the 2015 's most popular open source projects. After 12 iterations from v0.1 to v0.12, Google released its version of TensorFlow 1.0 on February 15, 2017, and hosted the first TensorFlow Dev Summit conference in Mountain View, California, USA.
About TensorFlow a very good article, reprinted from the "TensorFlow deep learning, an article is enough" click to open the link
Google is not only the leader in big data and cloud computing, but also has a good practice and accumulation in machine learning and deep learning, and at the end of 2015, open Source was used internally by the deep learning framework TensorF
In general, there are two functions for printing tensorflow variables:tf.trainable_variables () and Tf.all_variables ()The difference is:Tf.trainable_variables () refers to the variables that need to be trainedTf.all_variables () refers to all variables
In general, we are more concerned with training variables that need to be trained:It is important to note that the entire graph is initialized when the variable name is output
First, print the name of

AlphaGo: each experiment has 1000 nodes and each node has 4 GPUs and 4000 GPUs. Siri: 2 nodes and 8 GPUs for each experiment. AI research relies on massive data computing, instead of performance computing resources. The larger cluster running model shortens the weekly training time to the day-level hour level. Kubernetes, the most widely used container cluster management tool, distributed

At present the deep study is getting more and more fire, the related worker who learns, uses TensorFlow more and more.
