Q2. Given a set of one-dimensional training samples D = {x₁, x2, ..., 10} as follows: X4 x5 x6 x7 X8 Ig X10 x2 X3 0.24 -0.79 0.32 0.44 0.08 0.26 0.06 -0.71 0.65 X1 -0.17 (a) Suppose these data points are independently and identically sampled from N(μ, 1). Please estimate u by maximum-likelihood estimation and further calculate the mean squared error (MSE) between the estimated distribution p(x) ~ N(î, 1) and the ground-truth distribution p(x) ~ N(0, 1) over the given training samples, i.e., (p(xi) – p(x;))². (b) Given the window function 4(u) ~ N(0, 1) and hn = √, please estimate the probability density function (pdf) by the Parzen window method. Fur- thermore, please calculate the MSE between the estimated Parzen pdf and the ground-truth distribution over D. (Tips: It is recommended to write computer programs to calculate the MSEs.)
