还是接上一期，上一期中我们已经准备好了训练数据以及标签数据，这期我就来分享如何搭建神经网络，如何训练数据，以及验证数据。

由于系统的输出，其实是1~5分，每个分值的概率，并不是一个确定的数，我们可以选取概率最高的那一项作为最终判断依据。
同时由于评分系统，本身也是一个比较主观的判别，所以我这里假设“如果机器输出的评分与实际评分的差值在1分以内，那么就姑且认为，机器判断正确。”比如，机器评分是5分，实际评分4分，那么至少可以认为机器判断的大方向是正确的。

来看看最后测试的结果：

可以看到，有超过3/4的预测与实际评分相差1分以内，可以说明机器评分的在大方向上还是比较可靠的。

可以提高准确率的方法还有，这个在后一期中介绍。

来看看，整个建模过程：
打开昨天保存的训练数据和标签数据

with open('x_data.p', 'rb') as x:
x_data = pickle.load(x)
with open('y_data.p', 'rb') as y:
y_data = pickle.load(y)

复制代码

#建模，用全连接模型
model = Sequential()
#添加输入层，一共15207个词向量，提取1024个特征值（这个特征值的大小可以自己调试，会影响到最终的准确率，太少准确率会变差，但是速度会快。但是太高，准确率同样会变差，因为把每个值都当作特征，其实就等于没有特征了。）
model.add(Dense(1024, input_dim=15207))
#添加sigmoid激励函数
model.add(Activation('sigmoid'))
#添加隐藏层
model.add(Dense(1024))
#添加sigmoid激励函数
model.add(Activation('sigmoid'))
#再加隐藏层
model.add(Dense(512))
#添加relu激励函数
model.add(Activation('relu'))
#还是加隐藏层
model.add(Dense(512))
#添加relu激励函数
model.add(Activation('relu'))
#最终加输出层
model.add(Dense(5))
#添加softmax激励函数，用于分类
model.add(Activation('softmax'))
#编译模型，用RMSprop优化器，评价函数用categorical_crossentropy（与softmax搭配），增加准确率监控
model.compile(optimizer='rmsprop', loss='categorical_crossentropy', metrics=['accuracy'])
#训练模型，训练20次，每次1800多条数据
model.fit(x_data[200:, :], y_data[200:, :], batch_size=50, nb_epoch=20, verbose=True)
#保存训练结果
model.save('douban.h5')

复制代码

#用前200条数据进行测试

f = open('Predict_result.txt', 'w')
c = 0
for k in range(200):
temp = list(model.predict(x_data[k:k+1, :])[0])
score = temp.index(max(temp))+1
for i in range(5):
if y_data[k:k+1, :][0][i] == 1:
act_score = i+1
result = True if abs(act_score-score) <= 1 else False
if result: c += 1
print 'Number %d:' % (k+1)
print 'Predict Possibility:' , temp
print 'Predict Score: %d' % score
print ' Actual Score: %d' % act_score
print 'Predict almost correct:', result
print '-'*30
f.write('Number %d:' % (k+1) + '\n')
f.write('Predict Possibility:' + str(temp) + '\n')
f.write('Predict Score: %d' % score + '\n')
f.write(' Actual Score: %d' % act_score + '\n')
f.write('Predict almost correct:' + str(result) + '\n')
f.write('-'*50 + '\n')
print '%.1f percent predict almost correct.' % (c/2.0)
f.write('%.1f percent predict almost correct.' % (c/2.0))
f.close()

游客，如果您要查看本帖隐藏内容请回复

在下一期中，我会分享如何把这套系统运用到实际电影评分中去，如何把一段电影评论转化为电影评分，以及之后可以如何改良这套系统。

敬请期待！
