Aluminum Cold-Roll Durability Prediction

Final XGBoost Model with Preprocessing & Hyperparameter Optimization

This repository contains the full implementation and documentation for our Kaggle competition submission predicting y_passXtremeDurability, the probability that an aluminum cold-rolled sheet passes an extreme durability test.

Our final model used:

  • Data Cleaning and Preprocessing
  • Feature encoding including ordinal factors
  • Design matrices using model.matrix()
  • An initial XGBoost baseline model to establish an internal logloss benchmark
  • A hyperparameter grid search to identify the set with the lowest CV logloss
  • Final optimized XGBoost model and CSV output
