Virtual Assistant for Hôtel Le Belvédère

À propos du projet

Machine Learnia vacation workbook: building a virtual hotel front-desk assistant in three stages. First, a general-purpose LLM (Qwen2.5, open source, run locally) left to its own devices, caught hallucinating on things it didn't actually know. Then, the full hotel documentation added to the prompt, with a clear improvement but slower responses. Finally, a real RAG system (Retrieval-Augmented Generation, using sentence-transformers for embeddings) that only feeds the model relevant passages: accurate answers (hours, pricing, wifi), verifiable sources, and an honest refusal when a question falls outside the documentation.
