Deep Learning leverages multiple layers of neural networks to extract high-level features from raw input data. Which option best matches this characteristic?

• A. It relies on single-layer perceptrons.
• B. It uses rule-based feature engineering.
• C. It uses multiple layers of artificial neural networks to extract high-level features from raw input data.
• D. It focuses on linear regression only.

Answer: (C)

The main idea tested is how deep learning builds layered representations by stacking multiple neural network layers to learn features directly from raw data. In this approach, early layers pick up simple patterns, and deeper layers combine those into more abstract, high-level features. This hierarchy lets the model move from raw input to meaningful concepts without manual feature design, enabling powerful end-to-end learning across complex data like images or text. The option that describes multiple layers of artificial neural networks to extract high-level features from raw input data best matches this behavior. It captures the essence of deep learning: depth enables progressive abstraction and automatic feature extraction from raw data. Think about why the other options don’t fit. A single-layer perceptron can only learn linear boundaries and struggles with complex, non-linear patterns, so it can’t form deep, layered representations. Rule-based feature engineering relies on hand-crafted features rather than learning representations from data. Linear regression is a simple linear model with no hidden layers, so it can’t develop hierarchical, high-level features from raw input.
