I play with you to-very hot encryption and just have_dummies for the categorical details toward app investigation. For the nan-beliefs, we use Ycimpute library and you can expect nan values inside numerical parameters . Having outliers studies, i apply Regional Outlier Grounds (LOF) toward application data. LOF detects and surpress outliers study.
Each most recent financing in the application research have several prior funds. Per past software keeps one to line which can be identified by the latest element SK_ID_PREV.

We use get_dummies getting categorical details and you may aggregate so you’re able to (mean, minute, maximum, number, and you will sum) to have float parameters.
