Jun 1, 2025June 2025 — Merrimack_DSE6630 monthly summary. Focused on delivering robust analytics, standardized data pipelines for ML demos, and enriched spatial visuals to support decision-making. Key features delivered: - Pneumonia readmission analytics and modeling enhancements: refactored the Random Forest model, clarified justifications in the reporting, and improved results reporting to enable clearer risk stratification and actionability. - Demo_2 dataset provisioning and loading standardization: added readyTrain/readyTest datasets, standardized data loading paths, and updated file paths with data aggregation explanations to accelerate ML demos and reduce onboarding time. - Project 2 spatial data analysis and visualization: completed spatial data analysis, map visualizations, and mortality trend visuals, including metadata, shapefile components, projections, and QA annotations to improve interpretability and governance of results. Major bugs fixed: - No separate bug fixes logged this month; stability improvements were embedded within feature work (model refactor, data-path hardening, and QA clarifications) to reduce support tickets and ensure reproducibility. Overall impact and accomplishments: - Business value: clearer risk insights for pneumonia readmission, faster and more reliable ML demos through standardized datasets, and actionable spatial visuals to support public health decisions. - Technical achievements: improved model reliability and interpretability, robust data-loading pipelines, and comprehensive QA/metadata coverage for reproducible analyses. Technologies/skills demonstrated: - Python, scikit-learn (Random Forest), data engineering and pipeline hardening, geospatial analysis (metadata, shapefiles, projections), data visualization, QA annotations, and documentation for reproducibility.
