Personalized Visual Analytics for Multi-Criteria Decision Making

March 2025 – Present

University of Zürich

  • Identified shortcomings in current multi-criteria decision systems that lead to suboptimal, non-transparent rankings
  • Developed an interactive VA framework to capture complex user preferences via explicit inputs and implicit feedback
  • Engineered a prototype with advanced attribute scoring, uncertainty visualization, and LLM-powered natural-language explanations in a human-in-the-loop system
  • Established a scalable, transparent prototype improving decision accuracy and user trust for real-world applications

Evaluating the Stability of SHAP Under Class Imbalance

January 2024 – October 2024

University of Leeds

  • Developed and executed an experimental framework to assess the stability of SHAP values across machine learning models (SVM, KNN, Decision Trees, XGBoost) using imbalanced datasets
  • Developed SMOTE-Tomek hybrid sampling to create datasets with varying class imbalance ratios (1%, 5%, 10%, till 50%)
  • Introduced a novel metric, Coefficient of Variation (CV), for quantifying SHAP value stability
  • Generated visual insights using SHAP plots and box plots to communicate findings on feature importance stability
