Introduzione alla vector search: live coding di un'applicazione RAG in Java

🔍La vector search non è un concetto nuovo, ma i recenti sviluppi dei LLM hanno portato questa tecnica ad essere massivamente utilizzata in un numero crescente di contesti.
💻 In questa presentazione vedremo come funziona la vector search e un esempio pratico di utilizzo, scrivendo da zero un'applicazione RAG (Retrieval Augmented Generation) utilizzando Java ed Elasticsearch come vector store.
