Review Questions

• How does deep learning enhance the reconstruction of images compared to traditional methods?
  • Deep learning enhances image reconstruction by leveraging neural networks that can learn complex patterns and features from large datasets. Unlike traditional methods that may rely on predefined algorithms or assumptions about the data, deep learning approaches dynamically adjust based on the training data. This allows for better handling of noise and missing information, resulting in higher quality and more accurate reconstructions.
• Discuss the role of Generative Adversarial Networks (GANs) in the context of deep learning for reconstruction.
  • Generative Adversarial Networks (GANs) play a significant role in deep learning for reconstruction by generating new data samples that resemble real-world images. In reconstruction tasks, GANs can be utilized to create high-quality images from low-quality inputs by training on pairs of real and synthetic images. The generator works to produce realistic outputs while the discriminator assesses their authenticity, leading to continuous improvement in the quality of reconstructions throughout the training process.
