How do modern search systems find relevant information beyond exact keywords? How can AI applications use stored knowledge to answer questions accurately? This Specialization explores the technologies behind these capabilities, taking you from vector database fundamentals to building practical semantic search and Retrieval-Augmented Generation (RAG) applications.
By the end of this Specialization, you will be able to:
Generate embeddings, compare similarity metrics, and manage vector collections using ChromaDB.
Create Pinecone indexes, organise namespaces, filter records, and migrate vector data.
Prepare and chunk documents, develop retrieval pipelines, and integrate LangChain.
Develop RAG applications that generate grounded answers, provide sources, and handle missing context.
Evaluate retrieval accuracy, optimise search settings, and test database operations.
Secure credentials, manage errors and logs, and serve RAG applications using FastAPI.
Designed for aspiring AI engineers, Python developers, data scientists, and technology enthusiasts, this Specialization requires only basic familiarity with Python programming.
Through hands-on activities with Sentence Transformers, ChromaDB, Pinecone, LangChain, and FastAPI, you will progress from local vector search to a complete knowledge-base question-answering application.
Join us now and discover how to turn stored information into smarter search experiences and reliable AI-powered answers.
Applied Learning Project
Across this Specialization, you complete hands-on projects that reflect real-world vector search and RAG development. You begin by preparing product data, generating embeddings, and managing searchable collections in ChromaDB. Next, you work with Pinecone to configure indexes, organise namespaces, filter records, and create knowledge-base retrieval pipelines using LangChain. In the final project, you develop a RAG-powered support application that retrieves relevant information, generates grounded answers with source references, and handles insufficient context. You evaluate retrieval quality, optimise search settings, secure credentials, and expose the application through FastAPI. Each stage delivers practical outcomes, from vector collections and retrieval pipelines to a functional knowledge-base API, showcasing your ability to develop reliable RAG applications.
