先吐槽一下这个基于theano的keras有多难装，反正我是在windows下折腾到不行，所以自己装了一个双系统。这才感到linux系统的强大之初，难怪大公司都是用这个做开发，妹的，谁用谁知道啊！！！！ 
　　　先来介绍一下这个框架：我们都知道深度的神经网络，Python一开始有theano这个框架用来写神经网络，不过后来我们发现keras这个比theano更加容易构建，很适合初学者。×..× 
　　　以下是对应的英文网站：http://keras.io/#installation，英文好的话自己都可以看懂了。

一：先看安装

有两种： 
１．ubuntu下直接用　sudo pip install keras　安装 
２．又或者先安装以下的依赖项：

numpy, scipy
pyyaml
Theano
HDF5 and h5py

Once you have the dependencies installed, clone the repo:

git clone https://github.com/fchollet/keras.git

二.模块简介

１．optimizers: 
这个是用来选用优化方法的，里面有SGD，Adagrad，Adadelta，RMSprop，Adam可选

２．objectives 这个定义了用什么形式的误差来优化，有 
mean_squared_error / mse：平均方差 
mean_absolute_error / mae：绝对误差 
mean_absolute_percentage_error / mape：平均绝对百分差 
mean_squared_logarithmic_error / msle：对数误差 
squared_hinge 
hinge 
binary_crossentropy: Also known as logloss. 
categorical_crossentropy:使用这个目标函数需要设置label为二进制数组的形式。

３．model 
model = keras.models.Sequential() 初始化一个神经网络 
add 添加一层神经网 
compile(optimizer, loss, class_mode=”categorical”): 
参数： 
optimizer: str (优化函数的名称) 或者优化对象.参考 optimizers. 
loss: str (目标函数的名称) 或者目标函数. 参考 objectives. 
class_mode: 值为”categorical”, “binary”. 用于计算分类正确率或调用 predict_classes方法. 
theano_mode: A theano.compile.mode.Mode (reference). 
fit(X, y, batch_size=128, nb_epoch=100, verbose=1, validation_split=0., validation_data =None, shuffle=True, show_accuracy=False): 固定的 epochs训练一个模型. 
返回值：记录在字典中的训练成功的损失值，也可是验证损失值或精确度（适用的话）. 
参数： 
X: data. 
y: labels. 
batch_size: int. 每一次迭代的样本数目. 
nb_epoch: int. 
verbose: 0 表示不更新日志, 1 更新日志, 2 每个epoch一个进度行. 
validation_split: float (0 < x < 1).验证集的一部分. 
validation_data: tuple (X, y) 数据作为验证集. 将加载validation_split. 
shuffle: boolean. 每个 epoch是否随机抽取样本. 
show_accuracy: boolean. 每个epoch是否显示分类正确率. 
evaluate(X, y, batch_size=128, show_accuracy=False, verbose=1): 通过验证集的数据显示model的性能. 
Return: 返回数据的损失值. 
Arguments: 和上面fit函数定义相同. verbose用作二进制标识(进度条或无). 
predict(X, batch_size=128, verbose=1): 
Return: 测试数据的预测数组. 
Arguments: 和fit一样. 
predict_classes(X, batch_size=128, verbose=1): 返回test data的类预测数组. 
Return: 测试数据的标签数组. 
Arguments: 和fit一样. 
train(X, y, accuracy=False): 一个batch的梯度更新. if accuracy==False, return tuple (loss_on_batch, accuracy_on_batch). Else, return loss_on_batch. 
Return: 损失值, 或者tuple (loss, accuracy) if accuracy=True. 
test(X, y, accuracy=False): 一个batch的性能计算. if accuracy==False, return tuple (loss_on_batch, accuracy_on_batch). Else, return loss_on_batch. 
Return: 损失值, 或 tuple (loss, accuracy) if accuracy=True. 
save_weights(fname):保存所有层的权值到HDF5文件中. 
load_weights(fname): 加载保存在save_weights中模型权值. 只能加载相同结构的文件.

下面是自己写的一个小程序
