WebTaking the derivative with the respect to θ one can get: ∂ l ( θ) ∂ θ = n θ − ∑ i = 1 n ln ( x i) Second, you do not need to set it to zero (unless you are after the ML estimator). Moreover to compute the Cramer-Rao bound you need to take the second derivative: ∂ 2 l ( θ) ∂ θ 2 = − n θ 2. Then taking the expectation: Web实现rbf以及kriging等代理模型的构造并实现EGO算法优化.
