TensorFlow Learning Notes 4: Distributed TensorFlow
Brief Introduction
The TensorFlow API provides cluster, server, and supervisor to support distributed training of models.
The distributed training introduction about TensorFlow can refer to distributed TensorFlow. A simpl
Through a few routines, we gradually established a perceptual knowledge of tensorflow. This article will further from the internal principle of deep understanding, and then for reading source to lay a good foundation.1. Graph (graph)The TensorFlow calculation is abstracted as a forward graph that includes several nodes. As shown in the example:The corresponding TensorFl

The newly uploaded mcnn contains complete data read/write examples. For details, refer.
The official website provides three methods for Tensorflow to read data:
Feeding: each step of TensorFlow execution allows Python code to supply data.

software environment used in the study. For the last 4 years, open source software Torch7, the machine learning Library, has been our primary research platform, combining the perfect flexibility and very fast runtime execution to ensure rapid modeling. Our team is proud to have contributed to the open source project, which has evolved from the occasional bug fix to being the core maintainer of several key modules. With Google ' s recent open source release oftensorflow, we INITiated a project t
TensorFlow is a deep learning package developed by Google and is currently only supported on Linux and OSX. But this fall may have a Windows-enabled version of it, so for developers who use Windows, there's no need to wait for the fall or go to Linux and OSX TensorFlow. There are two ways to run on Windows, one is to install the virtual machine and install the Ubuntu system, install
TensorFlow Neural Network Optimization Strategy Learning, tensorflow Network Optimization
During the optimization of the neural network model, we will encounter many problems, such as how to set the learning rate. We can quickly approach the optimal solution in the early stage of training through exponential attenuation, after training, the system enters the optimal region stably. For the over-fitting probl

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:
Create a classifier for the iris dataset.
Load the sample data set and implement a simple binary classifier to predict whether a flower is an iris. There are

Use tensorflow to build CNN and tensorflow to build cnn
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:

TensorFlow can identify the image files that can be used via NumPy, using TF. Variable or tf.placeholder is loaded into the tensorflow, or it can be read by a function (Tf.read), and when there are too many image files, the pipeline is usually read using the method of the queue. Here are two ways to generate TensorFlow image formats, which provide input and outpu
The TensorFlow model is used to store/load the tensorflow model.

When we use an algorithm model online, we must first save the trained model. Tensorflow saves models in a different way than sklearn. sklearn is very direct. the dump and load methods of sklearn. externals. joblib can be sa
