The TensorFlow model is used to store/load the tensorflow model.
TensorFlow model saving/loading
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
TensorFlow realize Classic Depth Learning Network (4): TensorFlow realize ResNet
ResNet (Residual neural network)-He Keming residual, a team of Microsoft Paper Networks, has successfully trained 152-layer neural networks using residual unit to shine on ILSVRC 2015 , get the first place achievement, obtain 3.57% top-5 error rate, the effect is very outstanding. The structure of ResNet can accelerate the tra
Readers may recall the Tf.nn module in this series (ii) and (vi), the most concerned of which is the conv2d function.First, the blog (ii) MNIST routine convolutional.py key source list: DEF model (data, Train=false): "" "the model definition. " " # 2D convolution, with ' same ' padding (i.e. the output feature map has # the same size as the input). Note that {strides} is a 4D array whose # shape matches the data layout: [image index, y, x, depth]. CONV = tf.nn.conv2d (data,
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
This article provides examples of tensorflow's implementation of the elastic network Regression Algorithm for your reference. The specific content is as follows:
Python code:
# Using tensorflow to implement an elastic network algorithm (multi-variable) # using the iris d
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

I. TensorFlow variable Management
1. TensorFLow also provides the tf. get_variable function to create or obtain variables. When tf. variable is used to create variables, its functions are basically equivalent to tf. Variable. The initialization method
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:
Stride
Padding
Pooling

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

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

After I understand the tensorflow and then read this paragraph, I feel very clear, but before use to see this, really did not understand what meaning. Then I'll explain it in the most popular words. TensorFlow, English literal translation, tensor flow. So what is tensor? As the A
