SECTION ONE
1. What is the primary function of an activation function in a neural network?
A. To increase the number of layers in the model.
B. To reduce the training time of the model.
C. To introduce non-linearity into the network output.
D. To normalize the input data features.
, 🟢C
🔴 RATIONALE: Activation functions like ReLU or Sigmoid allow neural networks to learn complex
patterns by introducing non-linearity, without which the network would simply be a linear regression
model.
2. Which regulatory framework specifically addresses transparency and risk management for systems
in the European market?
A. GDPR
B. AI Act
C. CCPA
D. HIPAA
🟢B
🔴 RATIONALE: The EU AI Act is a specific regulatory framework designed to categorize and
manage the risks associated with various AI applications within the European Union.
3. In reinforcement learning, what does the exploration-exploitation trade-off refer to?
A. Balancing the discovery of new actions versus choosing known high-reward actions.
B. Choosing between supervised and unsupervised learning techniques.
C. Deciding whether to use a convolutional or recurrent architecture.
D. Managing the trade-off between model latency and accuracy.
🟢A
🔴 RATIONALE: Exploration involves trying new actions to find potential rewards, while exploitation
involves utilizing current knowledge to maximize known rewards.
4. Which metric is most appropriate for evaluating a model where the class distribution is highly
imbalanced?
A. Accuracy
B. F1-Score
, C. Mean Absolute Error
D. R-squared
🟢B
🔴 RATIONALE: F1-Score considers both precision and recall, providing a better measure of
performance than accuracy when one class significantly outweighs the other.
5. What is the primary purpose of dropout in deep learning?
A. To speed up gradient descent convergence.
B. To prevent overfitting by randomly disabling neurons during training.
C. To increase the memory capacity of the model.
D. To replace missing data points in the input set.
🟢B
🔴 RATIONALE: Dropout is a regularization technique that prevents neurons from co-adapting too
much, thereby reducing overfitting on training data.
6. Which technique is used to mitigate bias in training datasets?
A. Increasing the learning rate.
B. Oversampling underrepresented groups or undersampling overrepresented ones.
C. Removing all personal data from the entire database.
D. Changing the activation function to Softmax.
🟢B
🔴 RATIONALE: Data balancing techniques like SMOTE or undersampling help ensure the model is
exposed to a representative distribution of all target classes.
7. What does the term "model drift" describe?
A. The physical movement of a server hosting an AI model.
B. The degradation of model performance over time due to changing real-world data distributions.
C. The process of moving a model from a local environment to the cloud.
, D. The random initialization of weights in a neural network.
🟢B
🔴 RATIONALE: Model drift occurs when the statistical properties of the target variable, which the
model is trying to predict, change over time, rendering the model less accurate.
8. Which of the following is a classic example of an unsupervised learning task?
A. Predicting house prices based on historical sales.
B. Classifying emails as spam or not spam.
C. Clustering customers based on purchasing behavior.
D. Recognizing handwritten digits.
🟢C
🔴 RATIONALE: Clustering is an unsupervised task because it identifies groupings within data
without the use of pre-labeled target categories.
9. What is the core objective of the principle of "Data Minimization" in AI ethics?
A. To store as much data as possible for future analysis.
B. To collect only the data that is strictly necessary for the intended purpose.
C. To decrease the size of the neural network architecture.
D. To minimize the amount of time spent on data cleaning.
🟢B
🔴 RATIONALE: Data minimization is a foundational privacy principle requiring that organizations
only process the minimum amount of personal data required to achieve a specific task.
10. Which gradient descent variant computes the gradient using the entire dataset for each step?
A. Stochastic Gradient Descent
B. Mini-batch Gradient Descent
C. Batch Gradient Descent
D. Momentum-based Descent
