(a) noise will have an impact on VC bound?The answer is no.When noise is added to the signal, it has no intrinsic effect on what we have learned before.Did machine learning really work before? is based on the following: the source of training DataSet D is: (X,f (x)). where x is subordinate to a certain probability distribution p.What impact does noise have on data now? Previously, F (x) was determined. Now f (x) is uncertain. Because the presence of noise affects the value of f (x). At this poin
