Build a Multi-Agent CTR Prediction System with LangGraph

Build multi-agent click-through rate (CTR) prediction pipeline with LangGraph, scikit-learn, and OpenAI. Learn to orchestrate agents using LangGraph's StateGraph to preprocess data, train a machine learning model, and visualize results. Use a Random Forest Regressor to generate CTR predictions and shared agent state to pass data between pipeline stages. Integrate label encoding and standard scaling to prepare raw data for training, and generate scatter plot visualizations to evaluate model performance. Explore how LangGraph enables a fully automated machine learning pipeline.

Have you ever wondered how the ads you see online seem to know exactly when you're likely to click? Behind every ad placement is a machine learning model making a real-time prediction: will this user engage, or will they scroll past? In this project, you will build an AI-powered CTR (Click-Through Rate) prediction pipeline that automates the entire data science workflow — from raw, unprocessed advertising data all the way to a trained model and a visual evaluation of its performance. By orchestrating a team of specialized LangGraph agents and integrating OpenAI's GPT models, you will create a system where distinct AI roles collaborate to clean data, train a Random Forest model, and generate insight-rich visualizations. This project demonstrates the power of agentic workflows, where modular AI components hand work down a pipeline intelligently, transparently, and without manual intervention at every step.

What You'll Learn

By the end of this project, you will be able to:
  • Orchestrate Multi-Agent Systems with LangGraph: Define and manage specialized agents — an EDA Expert, a Statistician, and a Visualization Expert — each handling a distinct stage of a complex machine learning pipeline.
  • Integrate LLMs into Data Science Workflows: Connect your application to OpenAI's GPT-4o-mini model and understand how language models can power the reasoning layer of an automated pipeline.
  • Build Reusable ML Tools with LangChain: Use the @tool decorator to wrap data science functions as callable agent actions, making your preprocessing and training steps modular and independently testable.
  • Manage Shared Agent State: Learn how AgentState and LangGraph's StateGraph allow multiple agents to share data through a common pipeline without tightly coupling their logic.
  • Evaluate and Visualize Model Performance: Interpret Mean Squared Error (MSE) and scatter plots to assess how well your Random Forest model predicts CTR, and understand what the results tell you about your data.
  • Design Extensible Pipelines: Structure your workflow so that adding a new agent, swapping a model, or inserting a new preprocessing step requires minimal changes to the rest of the system.

Who Should Enroll

  • Python Developers looking to expand their skills into Generative AI, agent orchestration, and automated ML pipelines.
  • Data Science Beginners who want a hands-on introduction to the full machine learning workflow — preprocessing, training, and evaluation — within a structured, guided project.
  • AI Enthusiasts curious about how frameworks like LangGraph can simplify the creation of complex, multi-step AI behaviors without sacrificing clarity or control.
  • Software Engineers interested in understanding how agentic design patterns apply to real-world data tasks beyond chatbots and conversational interfaces.
  • Students and Educators seeking a practical, applied example of how modern AI tooling integrates with classical machine learning techniques.

Why Enroll

This project bridges the gap between traditional machine learning and modern agentic AI engineering. Instead of writing a single top-to-bottom script, you will design a collaborative system where each agent owns one responsibility and passes its result forward. You will move beyond basic model training to building a pipeline with structure, transparency, and personality — one where you can trace exactly what happened at every stage through a live message log.
By the end, you will have a working CTR prediction system, hands-on experience with LangGraph's StateGraph architecture, and a reusable template for building any kind of multi-step, automated data science pipeline. Whether you want to swap in a different dataset, plug in a new model, or extend the pipeline with hyperparameter tuning or automated reporting, this project gives you the foundation to do it confidently.

What You'll Need

To get the most out of this project, you should have:
  • Basic Python programming knowledge.
  • Familiarity with fundamental data science concepts like features, labels, and train/test splits (helpful but not required — everything is explained as you go).
  • Interest in Generative AI, machine learning automation, and modular software design.
  • [OPTIONAL] An OpenAI API key for LLM integration (our learning environment provides you an API key for free!)
All dependencies are installable via pip, and the project is compatible with standard Python environments on any current operating system.
