MACHINE LEARNING • LESSON 1 • FOUNDATIONS

What Is Machine Learning?

Machine Learning is a way of teaching computers to learn patterns from examples and use those patterns to make predictions or decisions.

But what does "learn from examples" actually mean?

Instead of giving the computer every rule manually, we give it examples and allow it to discover useful patterns in the data.

Let's Start With a Simple Idea

Imagine you want a computer to predict something.

For example:

  • Will this email be spam?
  • How much will this house cost?
  • Will this customer buy a product?
  • What will the temperature be tomorrow?

In each case, we want the computer to look at information and give us an answer.

In simple words: Machine Learning means learning from examples instead of manually writing every rule.

One Important Idea

The computer does not learn like a human.

It does not "understand" a house, an email, or a customer the way a person does.

It works with data and looks for patterns or relationships that can help it make useful predictions or decisions.

In this lesson, we will build this idea from the ground up.

We will start with a real-world problem, solve part of it ourselves, understand the mathematics behind it, and then use Python to build a simple Machine Learning model.

KEY IDEA

Machine Learning learns from examples.

Instead of manually writing every possible rule, we provide data and examples so the computer can discover patterns that can be used to make predictions or decisions.
