Personal experience: Feel Keras use is very convenient, at the same time the source code is very easy to read, we have to modify the algorithm, you can read the bottom of the source code, learning will not be like the bottom of the caffe so troublesome, personal feeling caffe the only advantage is that there are a lot of open model, the source code, ,
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

Before I have been using Theano, the previous five deeplearning related articles are also learning Theano some notes, at that time already feel Theano use up a little trouble, sometimes want to achieve a new structure, it will take a lot of time to programming, so think about the code modularity, Easy to reuse, but because it's too busy to do it. Recently discovered a framework called Keras, which coincides

1. About Keras
1) Introduction
Keras is a theano/tensorflow-based, in-depth learning framework written by pure Python.
Keras is a high level neural network API that supports fast experiments that can quickly turn your idea into a result, and you can choose
still very large. So in general, for the less complex verification code should choose a smaller network, only to encounter more complex verification code such as Chinese idioms, our experience is a complex network under the effect is better.In short, captcha recognition can be learned as a practiced hand project for deep learning, and it is easier to understand many of the concepts in
This article is mainly about the basic model of WaveNet and Keras code understanding, to help and I just into the pit and difficult to understand its code of small white.

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
