WebWe want to minimize the cost function J0(X0) defined by the formula J0(x0) = n ∑ k = 1‖x0 − xk‖2. The solution to this problem is given by x0 = m, where m is the sample mean m = 1 n ∑nk = 1xk. Proof. J0(x0) = ∑nk = 1‖(x0 − m) − (xk − m)‖2 = ∑nk = 1‖x0 − m‖2 − 2(x0 − m)T ∑nk = 1(xk − m) + ∑nk = 1‖xk − ... Web2 de fev. de 2024 · References . Park, K. (n.d.).
