这段代码使用了Python中的matplotlib库来绘制训练过程中的准确率和损失值的变化曲线。其中,history是一个字典,包含了训练过程中的各种指标值,比如accuracy和loss。plt.plot()函数用于绘制折线图,plt.title()用于设置图表标题,plt.ylabel()和plt.xlabel()则用于设置y轴和x轴的标签,plt.legend()用于设置图例位置和标签。最后,plt.show()用于显示图像。

plt.plot(history.history['accuracy'])
As an AI language model, I don't have access to the full context of your code. However, based on the function name plt.plot(), it is likely that you are trying to plot the accuracy of a model during training using the history object.
The history object is typically returned by the fit() method in Keras and contains information about the training process such as the loss and accuracy at each epoch.
The code snippet you provided is plotting the accuracy values over each epoch of the training process. This can be useful for visualizing how the accuracy of the model changes over time and identifying any overfitting or underfitting issues.
plt.plot(history.history[accuracy])
这是一段 Python 代码,用于绘制模型训练过程中的准确率(accuracy)变化曲线。其中,history是一个包含训练过程中各项指标的字典,accuracy是其中的一个指标。plt.plot()函数是Matplotlib库中的绘图函数,用于绘制折线图。这段代码的作用是将训练过程中的准确率变化可视化,以帮助分析模型的表现和优化训练过程。
