Let us slightly tweak the Least squares solution WReg = (XTX + γI)−1XTY . This is called Regularized least squares. On the face, it looks like we are simply adding noise to the diagonal. Will such a diagonal loading make it invertible? (Yes/No) ?

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

the answer on e2020 was d.
