Not a Black Box: How Explainable Machine Learning Transforms Lending and Saves Millions

Publication

I built a machine learning model that doesn’t just predict loan defaults—it explains why. By combining XGBoost with SHAP, I tackled challenges like class imbalance and made the model’s decisions more transparent and trustworthy.

The result? A system that could help lenders make smarter decisions, reduce defaults, and save millions 💵.

Applying Computer Vision to a Drawing Game

Publication

Used The Quick, Draw! Dataset from Google to build a CNN to predict which object the person drew. Using the webcam, our hands are the cursor to play the game, within the objective to make the Neural Network to guest which object you drew, given a certain object by the system. The user can select a pen, rubber among other things to draw in the screen.
