  • Summary

    This chapter showcases three domains different from the other domains to highlight particular techniques and problems missing from the previous chapters. Each domain uses a small dataset assembled just for the case study and undergoes only one featurization process. The first domain is video domain, where a mouse pointer tracking problem on a video is studied to showcase two key issues in feature engineering for video: speed of processing and reusability of results from a previous feature extraction. The second domain is geographical information systems, where bird migration data is studied to showcase the value of key points as physical summaries of paths and bi-dimensional clustering of points using R-trees. Finally, preference data is studied via movie preferences to showcase large scale imputation of missing features.
