So far, we’ve talked about:

1. what machine learning is

2. how models learn

But there’s still one important question:

**What are we actually trying to do with machine learning?**

Before choosing models or algorithms, we need to understand the **type of problem** we are solving.

## Let’s start with something simple: dough

Think about making dough. You start with similar base ingredients:

- flour

- water

- maybe salt

But depending on what you want to make, you prepare it differently.

- Soft dough → roti / chapati

- Elastic dough → pizza

- Fermented dough → sourdough bread

- Firm dough → certain breads

Same base idea. Different preparation. Different outcomes.

Machine learning works in a very similar way.

You may have the **same data**, but the **task you’re trying to solve changes everything**.
