The concepts of ‘gradient’ and ‘derivate’ are fundamental in mathematics, particularly in calculus. Both relate to how functions change, but they apply in different contexts and have distinct […]
Lagrange Multiplier
拉格朗日乘子(Lagrange Multiplier)用在含有等式约束的最优化问题中，如目标函数是$$f(x,y,…)$$，约束条件$g(x,y,…) = 0$，引入拉格朗日乘子$\lambda$用来协助求解使$f$最大或最小的解。
