Keras provides many common, prepared layer objects, such as the common convolution layer, the pool layer, and so on, which we can call directly through the following code:
# Call a conv2d layer
from Keras import layers
conv2d = Keras.layers.convolutional.Conv2D (filters,\ kernel_size
, \
strides= (1, 1), \
padding= ' valid ', \
...)
However, in practical applications, we often need to build some layer obje

minimum cost free. Specifically, network layer, loss function, optimizer, initialization strategy, activation function, regularization method are all independent modules, and you can use them to build your own model.
c) Scalability: It's super easy to add new modules, just write new classes or functions in the same mode as the existing ones. The convenience of creating new modules makes Keras more suitable
Install first and say:
sudo pip install Keras
or manually installed:
Download: Git clone git://github.com/fchollet/keras.git
Upload it to the appropriate machine.
Install: CD to the Keras folder and run the Install command:
sudo python setup.py install

Keras is a high-level neural network API written in Python that can be run TensorFlow, CNTK, or Theano as a backend. "Keras is more of an interface than an independent machine learning framework," said François Chollet, Keras's author, a Google engineer.
Keras allows for simple and rapid prototyping (user-friendly, highly modular, scalable) while supporting conv
Softmax is also placed in the activations module (I think it is more reasonable to put in the layers module). In addition, the newer activation functions, such as Leakyrelu and Prelu, are provided Keras in the Keras.layers.advanced_activations module.
InitializationsThis is the parameter initialization module, which initializes the call to Init when the layer is added.

Keras Introduction?? Keras is an open-source, high-level neural network API written by pure Python that can be based on TensorFlow, Theano, Mxnet, and CNTK. Keras is born to support rapid experimentation and can quickly turn your idea into a result. The Python version for Keras is: Python 2.7-3.6.??

Keras is a python library for deep learning that contains efficient numerical libraries Theano and TensorFlow.
The purpose of this article is to learn how to load data from CSV and make it available for keras use, how to model the data of multi-class classification using neural network, and how to use Scikit-learn to evaluate Keras neural network models.Preface,
