IN MATLAB, first correct answer will recieve thumbs up
2. Bias vs Variance in Estimation: Consider the problem of estimating the real value parameter w from the dataset Di with N points Here ni - 1.2, .....N are identical independently distributed zero-mean Gaussian noise samples of variance 2. Note that .. 2 and hence we can solve (2) with ri = I. It can also be shown that this corresponds to the maximum likelihood estimate, and hence we will denote the solution as We will analyze the performance of biased and unbiased estimators. Assume that w 2-0.1 for your MATLAB simulations. 0.04 andExplanation / Answer
[x,t] = simplefit_dataset;
net = fitnet(4);
rng(0)
[ net tr y e ] = train(net,x,t);
biaserr = mean(e(:))
varerr = var(e(:))
