Review Questions

• How does deep learning differentiate itself from traditional machine learning approaches?
  • Deep learning sets itself apart from traditional machine learning by its ability to automatically extract features from raw data without requiring manual intervention. While traditional methods often rely on hand-crafted features, deep learning uses neural networks with multiple layers to learn complex patterns directly from the data. This allows deep learning models to perform exceptionally well in tasks involving unstructured data like images or text, where traditional methods might struggle.
• Discuss the role of neural networks in deep learning and how they contribute to its effectiveness.
  • Neural networks are the backbone of deep learning systems, consisting of layers of interconnected nodes that mimic the way human brains process information. Each layer transforms the input data by applying weighted connections and activation functions, allowing the network to learn hierarchical representations. This structure enables deep learning models to capture intricate relationships within the data, leading to superior performance in tasks such as image classification and speech recognition compared to simpler models.
• Evaluate the impact of deep learning on various industries and predict future trends based on its current trajectory.
