Ensemble methods Data Mining Prof. Dr. Matei Demetrescu Statistics and Econometrics (CAU Kiel) Summer 2020 1 / 39 Moving further away from classical statistics So far, we proceeded as follows: 1 get (many) data, then 2 make a single – typically complex – predictor. 3 Don’t forget validating and testing the prediction model. We’ve also

CS 354 (Park) Midterm March 4 (Mon.), 2019 Remarks: Keep the answers compact, yet precise and to-the-point. Long-winded answers that do not address the key points are of limited value. Binary answers that give little indication of understanding are no good either. Time is not meant to be plentiful. Make sure not to get bogged
