STELLAR-RAG — Hybrid RAG Agent for University Documents Python 2026 GitHub: github.com/Khanhhh239/STELLAR_RAG
• Objective: A Vietnamese university Q&A system that answers questions about PDF documents.
• Techniques: Implement a hybrid retrieval mechanism fusing dense (bge-m3 + FAISS), sparse (BM25), and knowledge- graph searches via QDAP-S adaptive fusion. The architecture integrates an EHRAG entity hypergraph with diffusion re-scoring, a HybGRAG critic loop, Self-RAG, and Personalized PageRank (PPR) triple-hop traversal, managed by a 3-tier adaptive query router with Safety Alignment.
• Results: Produces grounded, citation-backed answers with low hallucination, evaluated on a 60-question benchmark using nDCG@10, grounding overlap, and an LLM-as-judge score. Machine Unlearning for Toxic LLMs Python / Jupyter 2026 GitHub: github.com/Khanhhh239/Machine_UnlearningToxic
• Objective: Research and implement 4 unlearning methods to remove toxic generation from an LLM without full retraining.
• Techniques: Implement four core techniques: Ethos (Task Arithmetic + SVD), NPO + RT (Negative Preference Optimisation), DEPN (Neuron Detection), and RMU + RNA (Representation Misdirection).
• Results: NPO+RT: toxicity score 0.19 0.0007 (−99.6%) Perplexity: 14.78 vs 13.88 baseline. Flow Matching — Generative Models: Theory to Practice Python / Jupyter 2026 GitHub: github.com/Khanhhh239/FLOW_MATCHING
• Objective: Implement Flow Matching (Continuous Normalizing Flows) end-to-end, scaling from 2D toy distributions to conditional CIFAR-10 image generation.
• Techniques: Vanilla + Rectified Flow with EMA on 8-Gaussian / Swiss Roll; evaluated with paper-level metrics
(Wasserstein-2, MMD, Straightness, NFE). Latent FM-DiT pipeline for CIFAR-10 with Classifier-Free Guidance and RK45 ODE solver; top-5 nearest-neighbour audit to rule out memorisation.
• Results: Toy (2D): Rectified Flow straightened trajectories from 0.95 0.99 and path efficiency 0.71 0.99 (kinetic energy 2.31 0.94) near-straight paths, far fewer solver steps to sample. CIFAR-10: Improved pipeline produces class-recognisable images with clear per-class semantic alignment (compared to noisy baseline outputs), staying stable across guidance scales 1.0–4.0.
