4. Features Preprocessing

. Preprocessing: encoding (ordinal and nominal categorical
  features, numerical features, cyclical features),
  full preprocessing pipeline;
. Feature Investigation: numerical features (
VIF to measure
  multicolinearity), ordinal features (spearman method),
  univariate feature selection (
SelectPercentile)

3. Baseline Pipeline

. Feature overview (numerical vs categorical features)
. Preprocessing (impute, scale, encode)
. Estimator (with DecisionTreeRegressor)
. Cross validation
. Prediction
