Review Questions

• How do deep learning models differ from traditional machine learning models in terms of data processing and feature extraction?
  • Deep learning models differ from traditional machine learning models primarily in their ability to automatically extract features from raw data. While traditional methods often require manual feature engineering and selection, deep learning utilizes multiple layers of neurons that can learn hierarchical representations directly from the data. This leads to improved performance on complex tasks such as image or speech recognition, where traditional models may struggle without extensive preprocessing.
• Evaluate the impact of deep learning models on technological advancements in areas like healthcare and renewable energy.
  • Deep learning models have significantly transformed technological advancements in various fields, including healthcare and renewable energy. In healthcare, they are used for tasks such as medical imaging analysis, helping to detect diseases with high accuracy and aiding in personalized treatment plans. In renewable energy, deep learning models optimize energy consumption and predict energy production from sources like wind and solar, contributing to more efficient systems and better resource management.
