What Is Machine Learning?
Student Name

Learning Objective
Machine learning is the branch of AI where computers learn patterns from data. Explore how it works, the three types of learning, and real examples.
Section 1 — What do you already know?
Before we begin, write down anything you already know about: Machine Learning
Section 2 — Key Concepts
1. What is machine learning?
Answer:
Machine learning is a type of artificial intelligence where computers learn patterns from data and use those patterns to make predictions or decisions — without being explicitly programmed for every situation.
2. How is machine learning different from AI?
Answer:
AI is the broad field of making computers perform intelligent tasks. Machine learning is one technique within AI — it is the method where computers learn from data rather than being given fixed rules.
3. What are the three types of machine learning?
Answer:
Supervised learning (learns from labelled examples — like a teacher marking homework), unsupervised learning (finds patterns in unlabelled data on its own), and reinforcement learning (learns by trial, error and rewards — like training a pet).
Section 3 — Check Your Understanding
Answer the following questions in your own words.
1. Define machine learning and distinguish it from traditional programming
2. Explain supervised, unsupervised, and reinforcement learning
3. Describe the ML training loop: data → model → prediction
4. Give real-world examples of machine learning in use
Section 4 — Fill in the Blanks
Complete the sentences using the concepts you have learned.
1. Machine Learning helps computers _________________ patterns from _________________.
2. The main difference between AI and a normal program is that AI _________________ from data rather than following fixed _________________.
3. One real-world example of Machine Learning is _________________, which uses it to _________________.
4. The inputs used by an AI model are called _________________ and the output it predicts is called a _________________.
Section 5 — Scenario Thinking
🤔 Think about this:
A healthcare organisation wants to use Machine Learning to assist doctors in diagnosing patients earlier. What data would the AI need? What challenges could arise? How can the team ensure the AI is fair, safe, and accurate?
Section 6 — What Did I Learn?
✅ Three key ideas I now understand:
❓ One question I still have:
⭐ Challenge Task
If you were designing an AI solution using Machine Learning, what problem would you solve? Outline a 3-step plan: (1) Problem statement, (2) Data to collect, (3) How to verify accuracy.
