f(w) B w It has two minima, labelled "A" and "B". Which of these minima has the smallest loss value? OB This minimum is known as the global minimum, as it has a smaller loss value than all other minima. The remaining minima are known as local minima, as they are only a minimum of the function in a local area. If the above function is denoted as f (w), then what is the value of the derivative, of f' (w) = dw at the points marked by A and B? Of'(A) = -1, f'(B) = 1 Unknown, but f'(A)
