使用训练好的模型进行预测
好的,我们可以使用飞桨(PaddlePaddle)框架训练和预测。首先,我们需要导入必要的库和模块:
```python
import paddle
import numpy as np
```
接下来,我们可以定义一个简单的全连接神经网络模型:
```python
class MyNet(paddle.nn.Layer):
def __init__(self):
super(MyNet, self).__init__()
self.fc1 = paddle.nn.Linear(6, 10)
self.fc2 = paddle.nn.Linear(10, 1)
def forward(self, x):
x = self.fc1(x)
x = paddle.nn.functional.relu(x)
x = self.fc2(x)
return x
```
定义好模型之后,我们可以加载数据集并进行训练:
```python
# 加载数据集
data = np.array([[[-6.23,-0.25,-5.46,1.59,-4.6,5.36],[4.58,4.34,4.9,8.49,6.35,14.25],[-0.631,-0.755,-0.959,-0.987,-1.083,-0.927]],-0.43],[[[ -0.25,-5.46, 1.59,-4.6,5.36,-0.43],[4.34,4.9,8.49,6.35,14.25,19.76],[-0.755,-0.959,-0.987,-1.083,-0.927,-0.783]],1.43]])
x_data = data[:, :-1, :].reshape(-1, 6).astype('float32')
y_data = data[:, -1, :].reshape(-1, 1).astype('float32')
# 定义数据读取器
def reader():
for i in range(len(x_data)):
yield x_data[i], y_data[i]
# 定义优化器和损失函数
model = MyNet()
opt = paddle.optimizer.Adam(learning_rate=0.01, parameters=model.parameters())
loss_fn = paddle.nn.MSELoss(reduction='mean')
# 训练模型
epochs = 1000
for epoch in range(epochs):
for x, y in paddle.batch(reader(), batch_size=1):
x = paddle.to_tensor(x)
y = paddle.to_tensor(y)
y_pred = model(x)
loss = loss_fn(y_pred, y)
loss.backward()
opt.step()
opt.clear_grad()
if epoch % 100 == 0:
print('Epoch {}, loss {}'.format(epoch, loss.numpy()))
```
训练完成后,我们就可以使用训练好的模型进行预测了:
```python
# 使用训练好的模型进行预测
x_test = np.array([[-3.14, 0.25, -1.5, 2.5, -2.8, 3.5]], dtype='float32')
model.eval()
predict = model(paddle.to_tensor(x_test))
print('Prediction:', predict.numpy())
```
请注意,上面的代码只是一个简单示例,实际应用中需要根据具体情况进行适当的修改。
