The Core Types of AI
Raghu Vijay Kowshik, Peter Jay Sorenson · 2026
In this chapter, we move past “what is artificial intelligence (AI)?” and look at what AI actually does . It does not just add up numbers or sort files. It solves problems, spots patterns, and adjusts on the fly . A famous moment showed this clearly: When AlphaGo beat a world champion using moves no human expected. That was not just a tech win. It was a sign that AI can think in new ways , not just copy us. Here we examine the type of AI and its evolution, the core characteristics of AI systems, and key applications using AI.
