Welcome to Unit 1: Introduction to Generative AI and Large Language Models
Welcome to Unit 1 of Generative Artificial Intelligence, where we begin our journey into the exciting and rapidly evolving world of Artificial Intelligence (AI), Generative AI, and Large Language Models (LLMs).
This unit provides students with a strong foundation in understanding the concept, scope, evolution, applications, and major technologies of Artificial Intelligence. The topics are explained in a simple, structured, and beginner-friendly manner, helping students understand how AI has evolved from traditional rule-based systems to modern generative approaches.
You will begin by exploring the definition and scope of Artificial Intelligence and understanding how AI enables computers and machines to perform tasks that traditionally require human intelligence. The unit also covers the historical background and major milestones in AI development, providing a clear picture of how the field has progressed over the years.
The unit further introduces different types of AI and explores real-world applications of AI across diverse fields such as Healthcare, Finance, Gaming, Education, Business, and other industries. These examples will help students understand the growing impact of AI in everyday life and modern technology.
A major focus of this unit is the introduction to Large Language Models (LLMs) and their role in Generative AI. Students will gain an overview of how LLMs process and generate human-like text and will be introduced to the fundamental concepts of Attention Mechanisms and Transformer Architecture, which form the technological foundation of many modern AI systems.
Finally, students will explore a comparative study of traditional rule-based systems and modern generative approaches, helping them understand the significant shift from predefined rules toward AI systems capable of generating new and meaningful content.
