在Python中,使用Keras或PyTorch这样的深度学习库来实现风机功率预测的CNN过程可能会按如下步骤进行:
1. **导入库**:
```python
import numpy as np
from keras.models import Sequential
from keras.layers import Conv1D, MaxPooling1D, Dense, Flatten
```
2. **数据预处理**:
```python
from sklearn.preprocessing import MinMaxScaler
scaler = MinMaxScaler()
# 对数据进行归一化
scaled_data = scaler.fit_transform(power_data)
```
3. **创建模型**:
```python
model = Sequential([
Conv1D(filters=32, kernel_size=3, activation='relu', input_shape=(sequence_length, num_features)),
MaxPooling1D(pool_size=2),
Flatten(),
Dense(64, activation='relu'),
Dense(1) # 输出层,预测一个值
])
```
4. **编译模型**:
```python
model.compile(optimizer='adam', loss='mean_squared_error')
```
5. **训练模型**:
```python
model.fit(X_train, y_train, epochs=50, validation_split=0.2)
```
6. **预测与评估**:
```python
predictions = model.predict(X_test)
rmse = np.sqrt(mean_squared_error(y_test, predictions))
```
