Please give me correct solution. πk= =8. Derive the EM algorithm for estimating the Gaussian mixture model p(X; 0)Σk_1 TkN (X; µk, Σk), where is the mixture weight with π ≥ 0 and Σk_₁ T 1, param-eters 0 = {Tk, Mk, k}_1, and N(x; µk, Ek) denotes the value of the Gaussian probabilitydensity function with mean μ and covariance matrix Σ evaluated at X = x. In the deriva-tion, first write down the Q function (the E step), and then derive the parameter updaterules by maximizing the Q function (the M step). You may resort to any material, but pleasewrite down your answer. (L + L)
