通常我们回选择非负数作为损失,且数值越小表示损失越小,完美与测试的损失为0,回归问题中最常用的损失函数是平方误差数。当样本ii的预测值为^yiy^i其对应的真是标签为y(i)y(i)时,平方误差可以定义为以下公式:$$l{(i)}(\boldsymbol{w},b)=\frac{1}{2}(\hat{y}-y{i})2\tag5$$...
Hence, {eq}\sqrt{x} {/eq} can also be defined as the number which, when squared, gives {eq}x {/eq} back. For example, {eq}\sqrt{x^2} = x {/eq} Example: {eq}\sqrt{4^2} = 4 {/eq} The square root symbol is also called the radical. Now, let's take the first ten ...
