My machine learning industry projects throughout the course in my Financial Engineering Program
- Built Gradient Boosting, Neural Network and Logistic Regression models after processing data and feature selection.
- Interpreted models to eliminate black box bias
- Ran grid search to fine tune the model's parameters and analyzed models stability (variance and bias).
- Sorted customers based on the probability of default estimated by each model, and segmented customers in to 10 bad rate buckets.
- Priced each buckets relevant interest rate and expected Net Present Value per segment.
While tuning the neural netwrok model for loan prediction for later use to segment customer in to bad rate buckets, I thought of how a preceptron with sigmoid activation function and SKLearn's Logistic regression model can give same/approximately lookalike performance by understanding common hyperparameters.
