First you need to download the data set by networking:
Mnsit = Input_data.read_data_sets (train_dir= './mnist_data ', one_hot=true)

Keras can be understood as a layer at the top of the TensorFlow, which can make some work simpler (and also support Theano backend).

ones.Some people has called Keras so good that it's effectively cheatingin machine learning. So if you ' re starting off with deep learning, go through the examples and documentation to get a feel for what can do With it. And if you want to learn, the start out with this tutorial and the see where you can go from there.The similar alternatives is lasagne and Blocks, but the they only run on Theano. So if you tried

Mxnet is the foundation, Gluon is the encapsulation, both like TensorFlow and Keras, but thanks to the dynamic graph mechanism, the interaction between the two is much more convenient than TensorFlow and Keras, its basic operation and pytorch very similar, but a lot of convenience, It's easy to get started with a pytorch

Image recognition is the mainstream application of deep learning today, and Keras is the easiest and most convenient deep learning framework for getting started, so you have to emphasize the speed of the image recognition and not grind it. This article allows you to break through five popular network structures in the shortest time, and quickly reach the forefront of image recognition technology.

powerful and flexible data frames of R into Python. For natural Language Processing (NLP), you can use the prestigious NLTK and lightning-fast spacy. For machine learning, there is an actual combat test of Scikit-learn. When it comes to deep learning, all the current libraries (Tensorflow,pytorch,chainer,apache Mxnet,theano, etc.) are the first projects implemented on Python.(on liveedu, a German AI developer teaches you how to develop two simple mac
efficient. An obvious trend is the use of modular structure, which can be seen in googlenet and ResNet, this is a good design example, the use of modular structure can reduce the design of our network space, and another point is that the use of bottlenecks in the module can reduce the computational capacity, which is also an advantage. This article does not mention some of the recent mobile-based lightweight CNN models, such as mobilenet,squeezenet,shufflenet, which are very small in size, and
this type of model.
3.3) Support Vector Machine (SVM)
For more information about SVM, see Professor Andrew Ng's CS229 on Coursera. (If you have the ability, visit the original CS229 on youtube or Netease open course ). The svm API documentation is very well-developed, and it is not very difficult to adjust the bag. However, in most data mining competitions (such as kaggle), SVM is often inferior to xgboost.

current classification method is the number of hidden layers to distinguish whether "depth". When the number of hidden layers in a neural network reaches more than 3 layers, it is called "deep neural Network" or "deep learning".Uh deep learning, it turns out to be so simple.If you have time, you are advised to play more in this playground. You will soon have a perceptual understanding of neural networks and deep learning.FrameworkThe engine behind the playground is Google's deep learning framew
