1. What type of machine learning approach is commonly used in recommendation systems that predict user preferences based on past behaviour, such as purchase or browsing history?
D. Semi-supervised Learning

Well done. Semi-supervised learning is sometimes used in recommendation systems when only a small subset of user data is labelled, and a larger portion is unlabelled.

2. Which of the following is the first step in the machine learning lifecycle?
D. Planning

Correct, well done! Planning is the first step in the machine learning lifecycle. This phase involves understanding the problem, setting objectives and determining the data and resources needed for the project.

3. In supervised learning, what is the key characteristic of the data used for training a model?
A. Data contains both input features and corresponding output labels.

That's correct, great job! In supervised learning, the key feature is labelled data. Each input has a corresponding output label, allowing the model to learn from this input-output relationship and generalise to new data.

4. Which machine learning methodology involves a system learning from feedback or rewards through trial and error?
C. Reinforcement Learning

That's right. Well done. Reinforcement learning is a methodology where an agent learns to take actions in an environment based on feedback received in the form of rewards or penalties, improving its decision-making over time.

5. Which of the following is a primary business value created by a machine learning-based recommendation system?
B. Increasing customer retention and sales

Great work! That's correct. Recommendation systems are designed to personalise the user experience, which helps increase customer engagement, retention and ultimately sales by recommending relevant products and services.

6. What is a potential challenge in using customer browsing history for training a recommendation system?
B. Data sparsity

Awesome job! Data sparsity refers to the challenge of not having enough data on new users or products to make accurate recommendations.

7. Which of the following correctly describes John McCarthy's role in the development of artificial intelligence (AI)?
B. John McCarthy coined the term ‘artificial intelligence’ in 1956 and was a key figure in the development of symbolic reasoning in AI.

Good job! John McCarthy is credited with coining the term 'artificial intelligence' in 1956, and he was instrumental in promoting symbolic reasoning as a core element of early AI research.

8. What is the relationship between machine learning (ML) and artificial intelligence (AI)?
A. ML is a subset of AI that focuses on learning from data, while AI encompasses all methods to simulate human-like intelligence.

Great answer! Yes, machine learning is a subset of AI, which focuses on algorithms that improve with experience (data). AI encompasses a wider range of techniques for simulating human-like intelligence.

9. In which stage of the machine learning lifecycle does model evaluation and validation take place?
C. Model Development

Way to go! Model evaluation and validation take place during the model development phase. In this phase, the model is trained, tested and validated to ensure it performs well.

10. Which stage of the machine learning lifecycle focuses on gathering, cleaning and transforming data to ensure it’s ready for model training?
C. Data Preparation

You got this! Data preparation is the stage where raw data is collected, cleaned and transformed into a format suitable for training machine learning models.
