Project #1 - Loanliness: Predicting Loan Repayment Ability by Using Machine Learning Methods
Key Notes
- Evaluating and predicting the repayment ability of the loaners is important for the banks to minimize the risk of loan payment default
Consumer Financial Protection Bureau rules
- Expected income or assets
- Employment status
- Expected monthly payment
- Monthly payment on the simultaneous loans
- Monthly payment of the mortgage
- Current debt status
- Residual income
- Credit history
Data Pre-processing
- Feature concatenation
- Feature Encoding and Normalization
- Invalid/Empty Entry Replacement
- Polynomial feature transformation
Summary - Data pre-processing, classification algorithms lessons
Code - Link
Project #2 - Detecting Credit Card Fraud with Machine Learning
Key Notes
Class imbalance solutions
- Undersampling – balances the data by randomly choosing observations from the majority class to exclude
- Oversampling – balances the data by randomly oversampling the minority class
- Both – a hybrid method that employs both undersampling and oversampling
- ROSE – a synthetic data generation method that balances the data by creating artificial samples of the minority class in the neighborhood of existing examples
Models
- Logistic Regression with Quadratic Terms and LASSO Regularization
- Simple Logistic Regression
- Random Forests
- Neural Networks
Summary - Handling imbalanced data, Applying different ML algos
Project #3 - Algorithmic Trading using LSTM-Models for Intraday Stock Predictions
Key Notes
- Feature Extraction - min-max-scalar
Keep Thinking!!!
