During my graduate practicum, my team developed python-based machine learning classification models, such as XGBoost and Random Forest, to classify text blocks within information request documents (e.g., RFPs) as questions, sections, or subsections. We applied various analytics techniques to enhance model performance and robustness, including addressing target variable class imbalance, performing dimensionality reduction, tuning hyper-parameters, and conducting cross-validation. Additionally… Show more During my graduate practicum, my team developed python-based machine learning classification models, such as XGBoost and Random Forest, to classify text blocks within information request documents (e.g., RFPs) as questions, sections, or subsections. We applied various analytics techniques to enhance model performance and robustness, including addressing target variable class imbalance, performing dimensionality reduction, tuning hyper-parameters, and conducting cross-validation. Additionally, we authored a comprehensive 20-page report that detailed our project approach, considerations, results, observations, trade-offs, and provided a business recommendation. Despite tight deadlines and limited subject matter expertise, we successfully delivered a final product that yielded encouraging results. Show less
