Vectara: End-to-End GenAI & Hybrid Search Platform
Architected an enterprise GenAI platform integrating hybrid retrieval (BM25 keyword + dense semantic embeddings), cross-attentional reranking, and citation-grounded RAG with automated hallucination scoring.
Cross-encoder reranking adds computational latency to large top-k query passes compared to pure bi-encoder dot-product search.
Hughes Hallucination Evaluation Model (HHEM)
Engineered an open-source factual consistency classifier calculating the precise probability that an LLM-generated summary hallucinated information not present in the reference context document.
Focuses on text summarization fidelity; does not evaluate arithmetic reasoning or multi-hop logical deductions.
