SECTION 1: INTRODUCTION TO MACHINE LEARNING (Questions 1-19)
Question 1
Which of the following best defines machine learning?
A. A system that follows explicitly programmed rules to complete tasks
B. A field of study that enables computers to learn from data without being explicitly programmed
C. A database management system that stores and retrieves information
D. A programming paradigm that uses object-oriented principles
,Correct Answer: B
Explanation: Machine learning enables systems to automatically learn and improve from experience
without explicit programming, distinguishing it from traditional rule-based systems.
Question 2
A researcher is developing a system to predict housing prices based on historical sales data. The dataset
contains labeled examples with known prices. Which type of learning paradigm is most appropriate?
A. Unsupervised learning
B. Reinforcement learning
C. Supervised learning
D. Semi-supervised learning
Correct Answer: C
,Explanation: Supervised learning uses labeled training data where input-output pairs are known, making
it ideal for regression tasks like price prediction.
Question 3
Which statement accurately describes the relationship between artificial intelligence, machine learning,
and deep learning?
A. They are synonymous terms referring to the same concept
B. Machine learning is a subset of deep learning, which is a subset of AI
C. Deep learning is a subset of machine learning, which is a subset of AI
D. AI is a subset of machine learning, which is a subset of deep learning
Correct Answer: C
Explanation: AI is the broadest field; machine learning is a subset of AI; deep learning is a specialized
subset of machine learning using neural networks.
Question 4
, In the context of machine learning, what does the term "feature" refer to?
A. The output variable being predicted
B. An individual measurable property of the data
C. The algorithm used for training
D. The error rate of the model
Correct Answer: B
Explanation: Features are input variables or attributes that describe the data and are used by models to
make predictions or decisions.
Question 5
A data scientist is working on a project to group customers based on purchasing behavior without any
predefined categories. Which learning approach should be used?
A. Supervised learning
