Approaches to solving :

1) Preparation
    - Import packages
    - Data loading

2) Preprocessing
    - missing values check
    - encoding (label + one-hot)

3) Analysis
    - the side of label : distribution (for detecting if imbalanced )
    - the side of features : visualization
    - label vs. features : correlation

4) Modeling
    - features selection
    - CatBoost finally ( compared w/ ExtraTree ) using label oversampling methods

5) Submission
    - CatBoost + SMOTE
