Concept learning is like learning how to group things into categories. Let's say we want to group animals into two categories: animals that have four legs and animals that have two legs. We can start by looking at a dog, which has four legs. We can then look at a bird, which has two legs. We can keep looking at different animals and figuring out which category they belong in. This helps us learn the concept of animals with four legs and animals with two legs. Some concepts can be more complicated, but the idea is the same: we look at examples of things and group them into categories based on their similarities.
