🔬 Research

📄 Applied Explainability for Large Language Models: A Comparative Study

Transformers are powerful — but why do they decide what they decide?

  • Dataset: SST-2 Sentiment | Model: DistilBERT
  • Implemented and rigorously benchmarked 3 XAI techniques:
    • 🟣 Integrated Gradients — token attribution via gradient paths
    • 🔵 Attention Rollout — propagated attention across transformer layers
    • 🟡 SHAP — game-theoretic local explanations
  • Evaluated stability, failure cases, and practical trade-offs for production ML systems
  • Goal: Make LLMs debuggable and transparent for industry deployment
