数值积分 使用scipy库的integrate.quad函数来计算拟合曲线下的面积。 fromscipyimportintegrate# 计算拟合曲线下的面积area,_=integrate.quad(fit_func,0,10,args=params)print(f'The area under the fitted curve is:{area:.2f}') 1. 2. 3. 4. 5. 6. 4. 类图 在这里,我们可以想象出一个类展示了我们如...
下面是输出结果的代码: print("The area under the curve is:",area) 1. 完整代码 下面是整个代码的完整实现: importnumpyasnpfromscipy.integrateimporttrapzdefcurve(x):returnx**2x=np.linspace(0,10,100)y=curve(x)area=trapz(y,x)print("The area under the curve is:",area) 1. 2. 3. 4. ...

接下来,我们需要计算在先验信念分布下,成功率至少为 33%的概率。为此,我们使用 SciPy 的 integrate 模块中的quad例程,该例程执行函数的数值积分。我们使用这个例程来积分 beta 分布的概率密度函数(在步骤 1中导入),并使用我们的先验参数。我们将根据我们的先验分布将概率打印到控制台上: ...
You can't simply put a linear area in the middle of the curve, that would introduce discontinuity and possibly large values in jerk.InstallationUsing pip (recommended):pip install s-curve-beta From source:git clone https://github.com/hidoba/s-curve-beta.git cd s-curve-beta python setup....

imbalanced-learn includes metrics and tools to evaluate model performance in the context of imbalanced datasets, such as precision-recall curves and the Area Under the Precision-Recall Curve (AUC-PR). Here's a basic example of using imbalanced-learn to balance a dataset using the Synthetic Minori...
