1) An error function to be minimined using gradient descent is given as E(w)=21[(w2w1)2+(1w1)2] (a) Find analytically the graticnt vector V(w)=[w1EwjE] (b) Find anulytically the weight vector w that minimines the error function sach thut FE(=)=0. (c) Based on part (a) draw the computed gradient vectors at three selected weight values in the given E(w1,w2) contour map plot given below. Superimpose the three vectors on the figure and check for consistency of the gradient vectors with the contours' direction and steepness
