WebTo keep the training set large, we allow validation sets that are small. The training sets overlap considerably, namely, any two training sets share K − 2 parts. ... Suppose we have a test dataset of 10 records with expected outcomes and a set of predictions from our classification algorithm. Long answer questions. WebWe can represent the function with a decision tree containing 8 nodes . (b)[2 points] Now represent this function as a sum of decision stumps (e.g. sgn(A)). How many terms do we need? F ANSWER: f(x) = sgn(A) + sgn(B) + sgn(C) Using a sum of decision stumps, we can represent this function using 3 terms .
