A company wants to predict future sales using historical data trends; which type of machine learning
approach is most appropriate?
A. Unsupervised learning using clustering
B. Supervised learning using regression
C. Reinforcement learning with rewards
D. Rule-based programming
Answer: B
Rationale: Regression models are used for predicting continuous numerical values like sales.
2.
A dataset contains missing values and inconsistent formatting before training a model; what is the most
appropriate first step?
A. Model deployment
B. Data preprocessing and cleaning
C. Increase model complexity
D. Skip validation
, Page 3 of 113
Answer: B
Rationale: Data must be cleaned before training to ensure accuracy.
3.
A model performs well on training data but poorly on unseen data; what is the most likely issue?
A. Underfitting
B. Overfitting
C. Data normalization
D. Feature scaling
Answer: B
Rationale: Overfitting occurs when a model memorizes training data but fails to generalize.
4.
Which AI technique is most appropriate for grouping customers based on purchasing behavior without
predefined labels?
, Page 4 of 113
A. Classification
B. Regression
C. Clustering
D. Reinforcement learning
Answer: C
Rationale: Clustering groups similar data points without labels.
5.
In a neural network, what is the primary role of weights and biases?
A. Store data permanently
B. Control how inputs are transformed into outputs
C. Replace activation functions
D. Normalize datasets
Answer: B
Rationale: Weights and biases determine how input signals are processed.
