Question

Based on the data provided below, answer questions from (1-4). We consider a function we wish to minimize. J(w)=110Σ5i(y(i)−w1x(i)−w0)2 where the constants x(i), y(i) are provided in the table below


i=1,2,3,4,5

x(i)=0,0.25,0.50,0.75,1.00

y(i)=1.4822,1.8165,1.9171,2.3930,2.5826


1) The dimension of w is _________.

1 point
