Let's spit it out. This is based on the Theano Keras how difficult to install, anyway, I am under Windows toss to not, so I installed a dual system. This just feel the powerful Linux system at the beginning, no wonder big companies are using this to do development, sister, who knows ah ....Let's start by introducing the framework: We all know the depth of the neural network, Python started with Theano this framework to write the neural network, but la

Download CUDA 8.0Address:
Keras If you are using the Theano back end, you should automatically do not use the GPU only CPU, start the GPU using Theano internal command.For the TensorFlow back end Keras and TensorFlow will automatically use the visible GPU, and I need it to run only on the CPU. Three methods were found on the web, and the last one was useful to me, but the following records were also made for three: using TensorFlow

Deep Learning
By now, your might already know machine learning, a branch in computer science that studies the "design of Algorithms" C An learn. Today, your ' re going to focus on deep learning, a subfield of machine learning This is a set of algorithms this is inspired By the structure and function of
1. Introduction Keras is a Theano based framework for deep learning, designed to refer to torch, written in Python, and is a highly modular neural network library that supports GPU and CPU. Keras Official document Address 2. Process First, use CNN for training, use the Theano function to remove the full link of the CNN, and train the SVM 3. Results Example Because this is just a demo
right: Actually, the right is a left-hand image on the time series of the expansion, the last moment output is the input of this moment. It is important to note that, in fact, all neurons on the right are the same neuron, the left, which share the same weights, but accept different inputs at each moment, and then output to the next moment as input. This is the information stored in the past.Understanding the meaning of "loops" is the purpose of this chapter, and the formulas and details are des
Installing Anaconda3
A key step:conda install pip
The following to install a variety of packages you need, generally no more error.pip install tensorflow-gpu ==1.5.0rc1pip install -U keras
If you need to install Theano, you need to install its dependency package, which isconda install mingw libpythonpip install -U theano
Install OpenCV3 (Windows environment):pip install -U opencv-contrib-python
Install TensorFlow
About Keras:Keras is a high-level neural network API, written in Python and capable of running on TENSORFLOW,CNTK or Theano.Use the command to install:Pip Install KerasSteps to implement deep learning in Keras

At the end of this two-week data mining class, project we selected is also a semantic segmentation of remote sensing images, so just the previous period of time to do the results of the reorganization and strengthen a bit, so
In Keras, a neural network visualization function plot is provided, and the visualization results can be saved locally. Plot use is as follows:

The Keras has many advantages, and building a model is quick and easy, but it is recommended to understand the basic principles of neural networks.

The main way to save the model section: one is through the JSON file
