有人问我是不是可以改代码，我说可以。

# 训练

我将NSL_KDD_Final_1.ipynb的代码改为了train.py，效果还不错。

![在这里插入图片描述](/static/img/images/03397.png)

前处理也是需要onehot编码：

![在这里插入图片描述](/static/img/images/03398.png)

也会归一化：

模型：

```cpp
# 双向RNN
batch_size = 32
model = Sequential()
model.add(Convolution1D(64, kernel_size=122, padding="same", activation="relu", input_shape=(122, 1)))
model.add(MaxPooling1D(pool_size=(5)))
model.add(BatchNormalization())
model.add(Bidirectional(LSTM(64, return_sequences=False)))
model.add(Reshape((128, 1), input_shape=(128,)))
model.add(MaxPooling1D(pool_size=(5)))
model.add(BatchNormalization())
model.add(Bidirectional(LSTM(128, return_sequences=False)))
model.add(Dropout(0.5))
model.add(Dense(5))
model.add(Activation('softmax'))
model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy'])
print(model.summary())
```
