Review Questions

• How does deep learning improve upon traditional machine learning techniques when analyzing complex data?
  • Deep learning improves upon traditional machine learning techniques by leveraging multi-layered neural networks that can learn hierarchical representations of data. Unlike traditional methods that often rely on manual feature extraction, deep learning models automatically discover important features through multiple layers of abstraction. This ability allows deep learning systems to handle complex tasks, such as image and speech recognition, with higher accuracy and efficiency.
• What role do neural networks play in the functionality of deep learning algorithms, and how do they differ from simpler models?
  • Neural networks serve as the backbone of deep learning algorithms, providing a structure that enables these systems to learn complex patterns within data. Unlike simpler models that may use linear regression or decision trees for predictions, neural networks consist of multiple interconnected layers that transform inputs into outputs through nonlinear functions. This multi-layered architecture allows deep learning models to capture intricate relationships and patterns in the data that simpler models might miss.
