如何调用agent.compile()函数
时间: 2023-06-09 16:06:50 浏览: 117
你可以调用agent.compile()函数来编译你的模型,它需要传入三个参数:优化器、损失函数和指标。例如:
```python
from tensorflow.keras import optimizers
optimizer = optimizers.Adam(lr=0.001)
agent.compile(optimizer=optimizer, loss='categorical_crossentropy', metrics=['accuracy'])
```
这样你就可以编译你的模型,开始训练了。

agent.compile(optimizer=optimizer, loss='categorical_crossentropy', metrics=['accuracy'])是什么意思
这段代码是在编译机器学习模型时使用的,其中 optimizer参数定义了优化算法,loss参数定义了模型优化过程中所使用的损失函数,metrics参数定义了模型评估时所使用的指标。在此代码中,模型将使用categorical_crossentropy作为损失函数进行优化,同时使用准确率作为评估指标。
解释:optimizer = optimizers.Adam(lr=0.001) agent.compile(optimizer=optimizer, loss='categorical_crossentropy', metrics=['accuracy'])
这段代码是在使用Keras搭建一个基于神经网络的模型时所用到的。其中,optimizer是模型的优化器,Adam表示使用Adam算法进行优化,lr=0.001表示学习率为0.001。loss代表损失函数,这里使用的是交叉熵损失函数。metrics代表评价指标,这里使用的是准确率来评估模型的性能。最终使用compile方法将优化器、损失函数和评价指标进行整合和配置后,将模型进行编译。
