Problem 4.2.

Please only do 4.2, I only need help with 4.2

. OVERFITTING 4.4 Problems pict the monomials of order i, фі(x-a". As you increase correspond to the intuitive notion of increasing complexity? Prob Problem 4.2 Consider the feature transform z = Lo(2), L1(x), L2(zr and the linear model h(x) w'z. For the hypothesis with w [1,-1, 1 what is h(z) explicitly as a function of z? What is its degree? Problem 4.3 The Legendre Polynomials are a family of orthogonal polynomials which are useful for regression. The first two Legendre Polynomals are Lo (z) = 1, Li (x) = x. The higher order Legendre Polynomials are defined by the recursion: 2k-1 k- 1 de n to
