About This Workshop
Retrieval-augmented generation (RAG) is a relatively new artificial intelligence technique that can improve the quality of OCI Generative AI service by allowing large language models (LLMs) to tap into additional data sources without retraining. AI Vector Search enables searching both structured and unstructured data by semantics or meaning and values, enabling ultra-sophisticated AI search applications.
This simple hands-on workshop can be executed in 90 minutes and consists of a basic example of AI Vector Search and the integration with OCI Generative AI service for RAG execution. It runs on Oracle Autonomous AI Database 26ai free tier or paid account. You can test any SQL statements and PL/SQL code with APEX AI Application Generator and SQL Developer Web.
You will learn how to run OCR on scanned documents and images containing text graphics to extract data for the embeddings. Besides PDF and Word documents, you can use JSON documents, such as GeoJSON shapes with geographical spatial information, which can be edited from the APEX demo application's GUI.
