Building Agentic RAG
Learn agentic RAG concepts and build custom tools that let LLMs autonomously retrieve and reason over knowledge. Master the ReAct framework to create agents and chatbots that iteratively plan, retrieve, and refine answers. Design stateful, graph-based agent workflows using LangGraph for production-ready agentic systems.

Prabhakaran S
Principal Data Scientist
My name is Selva, and I am super excited to mentor you on this course!
I head the Data Science team for a global Fortune 500 company and over the last 10 years of my data science experience I've deployed 20+ global products. I'm also the Founder and Chief Author of Machine Learning Plus, which has over 4M annual readers.
I specialize in covering the in-depth intuition and maths of any concept or algorithm. And based on my existing student requests, I've put up the series of courses and projects with detailed explanations, just like on-the-job experience. Hope you love it!
