I fool around with you to definitely-very hot encoding and have_dummies to the categorical details toward app investigation. Into nan-philosophy, we play with Ycimpute collection and you will predict nan philosophy from inside the numerical parameters . To possess outliers research, i pertain Local Outlier Basis (LOF) on the application study. LOF detects and you will surpress outliers study.
Each most recent financing about software analysis have several earlier fund. For each prior application have you to definitely row that will be identified by the new ability SK_ID_PREV.
