Keras Learning Notes

Keras and the use of Torch7 is very similar to the recent fire up the depth of the open source Library, the bottom is used Theano. Keras can be said to be a python version of Torch7, very handy for building a CNN

Python vector:
Import NumPy as np
a = Np.array ([[[1,2],[3,4],[5,6]])
SUM0 = Np.sum (A, axis=0)
sum1 = Np.sum (A, Axis=1)
PR int SUM0
Print sum1
> Results:
[9 12][3 7] Dropout
In the training process of the deep Learning Network, for the Neural network unit, it is temporarily discarded from the network according to certain probability.Dropout is a big kill for CNN to prevent the effect of fitting. Output

RNN model of deep learning--keras training
RNN principle: (Recurrent neural Networks) cyclic neural network. It interacts with each neuron in the hidden layer and is able to handle the problems associated with the input and back. In RNN, the output from the previous moment is passed along with the input of the next moment, which is equivalent to a stream of data

Python
TensorFlow

Here we choose TensorFlow as the back-end tool for Keras. Use the following Python code to output the version numbers of Python, TensorFlow, and Keras:import sysimport
