I want the solution to this complicatedproblem please.

Probability density function (pdf) p(z|^2,q) = q / [(2(2*(^2))*(1/q)*(1/q))] *e^(|z|q 22). If y = f(x)+z, in which z denotes random noise following the above pdf. Write out the log likelihood function logp(y|X,2,q) with respect to f(x), 2 and q given the training data X = {x1,x2,...,xN} and y = {y1,y2,...,yN}.
