The data is now prepared for training. Logistic Regression was chosen as the baseline model. The strategy focuses on achieving high Recall for the fraud class, as the standard Accuracy metric is misleading due to the severe imbalance. The use of SMOTE and RobustScaler is essential to ensure the model successfully identifies the rare fraud cases.
