Featured Work

Predicting Undergraduate Admission Outcomes in Bangladesh

Developed and deployed a machine learning model to predict undergraduate admission outcomes in Bangladesh. Achieved 83.87% accuracy and 0.8633 ROC-AUC by optimizing feature selection and hyperparameter tuning. Conducted SHAP analysis to identify key predictors (e.g., family support, GPA), providing actionable insights.

Environmental Determinants of Diarrheal Disease

Built and compared multiple regression models (Linear Regression, Random Forest, SVR, Decision Tree, Gradient Boost) for disease trend prediction. Incorporated lagged features 0-7 days to achieve best performance with Linear Regression RMSE: 7.40, MSE: 54.82. Analyzed time-series data across four major divisions to identify key environmental correlations. Designed an interactive dashboard with real-time visualizations for insights.
