2. Implicitly defined Population Attributes (a) (5 marks) Given a population P = {(C,, 3,), .... (IN, UN)}, consider the problem of calculating B for the regression through origin, i.e. yu = BI + Tu. We would like to calculate the parameter S of this model using N for |r| p(7.) where PK(T) =k |7 - }k2, otherwise. Using bullet points, describe the gradient descent algorithm to find S in this particular problem. Any function/derivative should be calculated explicitly as the p function has been provided in the
