During the first day, the key instruments used for modelling are explored. A wide use of the software R characterizes the course from the very beginning. In day one, the emphasis is on familiarizing with Machine Learning techniques and R programming. Indeed, an extensive interaction with R paves the way for the next three-day program.
The focus of the second day is on PD modelling. Starting from an introduction to scorecard one-year modelling, a series of Machine Learning techniques is introduces. Focus is mainly on classification and regression trees, bagging, boosting, and random forest. Hints are also provided on reinforcement learning. A time horizon expansion to encompass the entire lifetime characterizes the second part of the day where survival analysis is introduced and a combination of machine learning techniques is explored by means of R software.
The third day covers both EAD and LGD modelling. A series of approaches is investigated by means of machine learning techniques studied during Day 1 and Day 2. Behavioural model encompassing prepayment, overpayment and a comprehensive EAD dynamic are studied through the lenses of bagging, boosting and random forest modelling. Similarly, LGD is explored by considering both traditional approaches like logit, tobit models as well as through Machine Learning toolkit.
