What is generalization?

Generalization is when you take something you already know and use it to understand new things.

Imagine you’ve seen a dog before, maybe your neighbor’s big black dog who always barks at the mailman. Now, one day, you see a small white dog in the park. Even though this dog looks different from the one you know, you still say, “Oh, that’s a dog too!” You’re using what you already know about dogs to figure out something new, and that's generalization.

Think of generalization like learning how to recognize your favorite toy in different colors. If you love red cars, and one day you see a blue car, you might still say it’s a car because you’ve seen many kinds before. You're using the same idea, just with a different color.

Generalization helps you learn faster. When you know that all dogs are similar in some way, you can figure out new things about dogs without learning everything from scratch each time. It’s like having a special tool for learning!
