我刚开始使用matplotlib进行可视化,我想绘制一张机器学习模型的预测值与实际值的图。
我做了一个预测使用随机森林算法,并希望可视化的真实值和预测值的绘图。
我使用了下面的代码,但是图没有清楚地显示预测值和实际值之间的关系。
plt.scatter(y_test1, y_pred_test_Forestreg)
plt.xlabel('True Values ')
plt.ylabel('Predictions ')
plt.axis('equal')
plt.axis('square')
plt.xlim([0, plt.xlim()])
plt.ylim([0, plt.ylim()])
_ = plt.plot([-100, 100], [-100, 100])
这是我得到的:
这是我所期望的情节:
下面是我想要绘制的数据表。(注:这只是结果的一部分,因为它是不可能包括完整的数据(形状8221,1)在这里。我期待着你的帮助。

这是我试图理解你的问题,并得到你真正想要的东西,所以假设我们手边有true_value和predicted_value,我会把它们画成这样:
结果是:
你是否正在寻找这样的东西,是的,我使用对数轴,因为你的值的尺度不同。
希望这是你想要的。

问题是您的值范围从0到60.000。我建议您选择两个选项:您可以将两个轴都转换为对数刻度
或者,更好的是,绘制真实值和预测值之间的差异(即预测误差)。
eyh26e7m3#
我建议重新调整你的值,因为值太分散了。虽然你的大多数条目小于50,但规模高达60000。一旦你重新调整了你的条目,让我们说0 - 1规模,然后它应该看起来更好。我会使用某种规模。
q3qa4bjr4#
实际上,你可以从这个散点图中获取第一个基本信息:这个模型在极高的输入值上有真实的差的预测。这里的Rmse会很高,你已经可以总结出这个模型很差(如果这些高输入值和低输入值一样重要的话)。如果你不关心高输入值,那么你可以简单地在一个更小的域中查看这个图,改变你的
x
和ylim
。用相同的因子线性地重新缩放它们,只会产生相同的散点图,但带有不同的标签。你可以将它们归一化到它们的最大值,但我不知道你的散点图的可读性会如何。
如果您的目的只是更好地可视化结果,则可以对实际值和预测值应用一些非线性变换(db?gamma校正?)。
ycggw6v25#
要绘制预测标签与实际标签的对比图,我将执行以下操作:
1.假设这些是参数的名称
X_features_main #The X Features
y_label_main #The Y Label
y_predicted_from_X_features_main #The predicted Y-label from X-features I used
