Task : Regularized Regression
Given the values of an unknown function : at some selected points, we try to calculate the
parameters of a model function using OLS as a distance and a ridge regularization:
if : a polynomial model function of twelve parameters:
cdots
if : a polynomial model function of oj: parameters: ;oj:
cdots
Calculate the OLS estimate, and the OLS ridgeregularized estimates for the parameters given the
sample points of the graph of given that the values are What weight do you give to the
penalties? What are the qualities of each of the solutions?
Remember to include the steps of your computation, as these are more important than the actual
computations. If you calculate the solution with a program, make sure that you trust and cite the core
functions used and that you sketch the mathematical path in a way that is coherent with the program.
