Project Description
📄 From Refusal Tokens to Refusal Control Categorical steering vectors for LLM refusal control. −13.70% over-refusal, +14.17% harmful refusal on LLaMA-3 8B. 🎉 NeurIPS 2025 MechInterp Workshop · Under review ICML 2026
🖊️ Sketch2Graphviz Converts sketches/images of graphs into Graphviz code via LoRA fine-tuned Llama 3.2 11B Vision + RAG over a PostgreSQL/PGVector vector DB
⚙️ AutoNeuroNet Custom C++ library with Python bindings for autograd, matrix ops, and neural networks — built from scratch
🔍 GitLensAI AI-powered Git intelligence tool for natural language querying of repository history, commit analysis, and developer insights
