log(P|x)越大,-log(P|x)就越小,因此我们可以把-log(P|x)看作损失函数: L=−log(P|x)=−ylogy^−(1−y)log(1−y^) 这就是交叉熵损失函数的简单推导。 损失函数(Loss Function)是定义在单个训练样本上的,即单个样本预测值与实际值的误差,我们在整个训练样本上定义代价函数(Cost Fcuntion...

In step one, data clustering algorithms are applied to build a classier model for identifying the distinct electrofacies (EF) based on similarity of well log responses. In step two, a distinct and specialized regression model is selected from more sophisticated methods (empirical models, ...
