Keras is a Theano and TensorFlow-compatible neural network Premium package that uses him to component a neural network more quickly, and several statements are done. and a wide range of compatibility allows Keras to run unhindered on Windows and MacOS or Linux.Today to compare learning to use Keras to build the following common neural network:

The biggest problem with full-attached neural networks (Fully connected neural network) is that there are too many parameters for the full-connection layer. In addition to slowing down the calculation, it is easy to cause overfitting problems. Therefore, a more reasonable neural network structure is needed to effectively reduce the number of parameters in the neural network. convolutional Neural Networks (convolutional neural network,cnn) can do that.

In order to enhance the understanding and use of CNN, this blog post, in order to communicate with people, mutual gain. Before the text, say a
Introduction to convolutional Neural Networks
Convolutional neural network is a multi-layer neural network that specializes in processing machine learning problems related to images, especially big images.
The most typical convolutional network consists of a convolution layer, a pooling layer, and a full connection layer. The convolution layer works with the pooling layer to form multiple convolution groups, extract features layer by layer, and finally complete classification through several ful

But, in general, we need a powerful machine to run the CNN, we just need to use the resulting results for the mobile side.
