Foundational Understanding of Generative AI
Generative AI is transforming healthcare by creating new data rather than just analyzing existing information. This unit explores its foundational principles, the infrastructure behind it (GPUs/TPUs, training of large language models), its historical evolution, practical clinical applications, and the ethical and sustainability considerations that come with it.

- Explain the fundamental principles of Generative AI and how it differs from traditional AI models in healthcare.
- Analyze how Generative AI can enhance clinical workflows — documentation, decision support, and patient interactions.
- Evaluate the hardware and computational requirements for training and deploying Generative AI models in healthcare.
- Assess the energy/sustainability concerns of large AI models and strategies to optimize efficiency.
- Describe the training process of large language models (backpropagation, gradient descent, fine-tuning).
- Compare building proprietary models vs. leveraging pre-trained or open-source alternatives.
- Investigate the historical evolution of Generative AI, including OpenAI's role.
- Synthesize emerging trends and predict future developments in medicine.
- Formulate strategies for integrating Generative AI while addressing ethics, privacy, and legal constraints.
