T81 559:Applications of Generative Artificial Intelligence

Washington University in St. Louis

Instructor: Jeff Heaton

• Section 1. Spring 2025, Wednesday, 6:00 PM, Location: January Hall / 10

Course Description

This course covers the dynamic world of Generative Artificial Intelligence providing hands-on practical applications of Large Language Models (LLMs) and advanced text-to-image networks. Using Python as the primary tool, students will interact with OpenAI's models for both text and images. The course begins with a solid foundation in generative AI principles, moving swiftly into the utilization of LangChain for model-agnostic access and the management of prompts, indexes, chains, and agents. A significant focus is placed on the integration of the Retrieval-Augmented Generation (RAG) model with graph databases, unlocking new possibilities in AI applications.

As the course progresses, students will delve into sophisticated image generation and augmentation techniques, including LORA (LOw-Rank Adaptation), and learn the art of fine-tuning generative neural networks for specific needs. The final part of the course is dedicated to mastering prompt engineering, a critical skill for optimizing the efficiency and creativity of AI outputs. Ideal for students, researchers, and professionals in computer science or related fields, this course offers a transformative learning experience where technology meets creativity, paving the way for innovative applications in the realm of Generative AI.

Note: This course will require the purchase of up to $100 in OpenAI API credits to complete the course.

Objectives

1. Learn how Generative AI fits into the landscape of deep learning and predictive AI.
2. Be able to create ChatBots, Agents, and other LLM-based automation assistants.
3. Understand how to make use of image generative AI programatically.
