This chapter introduces the techniques used to abstract the data from low-level data to features that can be used to visualize and develop models to inform the different stakeholders. These techniques range from (a) knowledge engineering, where expert knowledge is used to develop formulae to compute various measures from low-level data; (b) feature selection, where specific important variables are selected from the list of low-level data variables as they may be deemed more important than other; and (c) feature extraction, where features are computed statistically through combining various measures from low-level data. The chapter also includes labs where, using real game data, you get to apply the discussed techniques.
