Some equations may have the variable on both sides of the equal sign, as in this equation: 4x−6=2x+104x−6=2x+10.To solve this equation, we need to “move” one of the variable terms. This can make it diffic
线性代数有一种计算代价函数𝐽最小值的数值解法,不需要梯度下降这种迭代算法,它可以在不需要多步梯度下降的情况下,也能解出代价函数𝐽的最小值,这是另一种称为正规方程(normal equations)的方法。实际上在数据量较大的情况下,梯度下降法比正规方程要更适用一些 2.8接下来的内容 通过线性代数,可以实现和使用更强...
在后面的课程中,我们也会谈到这个方法,它可以在不需要多步梯度下降的情况下,也能解出代价函数J的最小值,这是另一种称为正规方程(normal equations)的方法。实际上在数据量较大的情况下,梯度下降法比正规方程要更适用一些。 q
