Which of the following tasks belongs to Data Science but not strictly to Machine Learning?
Correct Answer: B
Explanation:
Data Science covers a broader lifecycle including data cleaning, exploration, visualization, and interpretation. EDA is about summarizing main characteristics of datasets and visualizing trends before modeling. Gradient descent and optimization belong specifically to ML modeling. Feature engineering overlaps both domains but is heavily modeling-driven.
Question 2
Deep Learning differs from traditional ML because:
Correct Answer: C
Explanation:
Deep Learning is a subset of ML using neural networks with many hidden layers. These layers automatically extract hierarchical features, unlike classical ML that depends heavily on manual feature engineering. Deep Learning is particularly powerful in image recognition, NLP, and speech processing due to this automatic representation learning.
Question 3
In an AI project cycle, what comes immediately after the problem scoping stage?
Correct Answer: A
Explanation:
The AI project cycle typically follows Problem Scoping → Data Acquisition → Data Exploration → Modeling → Evaluation → Deployment. After defining the problem and scope, gathering relevant and quality data is crucial, as models rely heavily on the correctness and completeness of input data.
