Approach

In this notebook we use the following concepts and methods:

• Undersampling and oversampling.
• Outlier detection.
• Anomaly detection with autoencoders.
• Gaussian Naive Bayes.
• Gradient boosted trees (XGB and LGBM), with grod-search and cross-validation.
• Bayesian hyperparameter optimization.
• Model blending for improved AUC scores.
