Related to Legendre polynomials
In lect 12, we learn the regularization for a nonlinear transformation which is
composed of Legendre polynomials. But then in hw6, Q2 to Q6, The nonlinear transform doesn't talk anything about Legendre polynomials. Does it mean, Legendre polynomials is used in deriving the theory, and any function, including the in hw6, can actually be expressed in terms of Legendre polynomials ? Further, does it only hold true for the range 1 to 1 ?

Re: Related to Legendre polynomials
Thank you very much for the prompt reply. Does it mean that if we want to use
this regulariser, then we need to normalise the input data to range 1 to 1 ?
