1. What is Machine Learning

Machine learning is a type of artificial intelligence that

• Can make decisions without being explicitly programmed.
• Can recognise patterns in data

• Can learn from experience
• All of the above

Which of the following is NOT an example of machine learning:

• A spam filter that learns to identify spam emails.
• A calculator
• A self-driving car that learns to navigate roads.
• A music recommendation system that learns your taste in music

Machine learning algorithms are trained on:

• A. Data
• B. Code
• C. Instructions
• A and B

Once a machine learning algorithm is trained, it can be used to:

• Make predictions
• Classify data
• Cluster data
• All of the above

One of the biggest challenges in machine learning is:

• Collecting enough data
• Training the algorithms
• Deploying the algorithms
• All of the above

Machine learning is being used in a wide variety of industries, including:

• Technology
• Healthcare
• Finance
• All of the above

Which of the following is NOT a benefit of machine learning

• It can automate tasks
• It can improve decision-making
• It can replace human workers
• It can create new products and services

Machine learning is a powerful tool, but it is important to use it responsibly. Ways to do this include (you must select all three correct options)

• Give users control over their data
• Be transparent about how machine learning is being used
• Build safeguards against bias and discrimination
• Don't bother getting out of bed in the morning and let the computers decide everything
• Allowing the companies to have all the users data and be able to sell it

Which of the following is a famous example of a machine learning algorithm:

• AlphaGo
• GPT-5

• DALL-E 3

• All of the above

The future of machine learning is bright. It has the potential to ( (you must select all three correct options)):

• Solve some of the world's biggest challenges
• Improve our lives in many ways
• Eat ham sandwiches
• Create new jobs and industries
• Become an international BMX Bike rider
