好的,以下是一个简单的缺陷检测的 TensorFlow 代码示例:
首先,我们需要导入 TensorFlow 库及其相关组件:
```python
import tensorflow as tf
from tensorflow.keras.layers import Conv2D, MaxPooling2D, Flatten, Dense
from tensorflow.keras.optimizers import Adam
```
然后准备训练数据和标签:
```python
train_data = ... # 用于训练的图像数据
train_labels = ... # 对应的标签
```
接着,定义模型架构:
```python
model = tf.keras.Sequential([
Conv2D(32, (3, 3), activation='relu', input_shape=(None, None, 3)),
MaxPooling2D((2, 2)),
Conv2D(64, (3, 3), activation='relu'),
MaxPooling2D((2, 2)),
Conv2D(128, (3, 3), activation='relu'),
MaxPooling2D((2, 2)),
Flatten(),
Dense(128, activation='relu'),
Dense(1, activation='sigmoid')
])
```
定义优化器:
```python
optimizer = Adam(lr=0.001)
```
编译模型:
```python
model.compile(optimizer=optimizer,
loss='binary_crossentropy',
metrics=['accuracy'])
```
训练模型:
```python
model.fit(train_data, train_labels, epochs=10)
```
以上只是一个简单的示例,实际应用中需要根据具体需求进行调整和改进。
