(Hint) Consider a number of unknowns greater than the number of examples. 17. [M25] In Section3.2.3we discuss the separation failure when we combine linear units and the quadratic error. Now let us consider the genericp-norm E(wˆ)=(∑κ=1ℓ(yκ−f(xκ))p)1/p. ...
,nk∈R,n is a nonnegative integer, and the summation is taken over all k-tuples of nonnegative integers n1,…,nk with n1+⋯+nk=n, is called a polynomial in x1,…,xk. Show that if E is a compact subset of Rk then the polynomials in x1,…,xk are dense in C(E). 6.20 ...
