Worked Example: Prompt Engineering for Text Generation

Scenario: You want to generate a short article summary using an LLM.

Solution:

1. Curate a dataset of articles and their summaries for training.
2. Select a suitable text embedding model for your use case.
3. Apply prompt engineering principles to create a prompt that guides the LLM to generate a concise summary while preserving key details.
4. Fine-tune the LLM on your dataset using the prompt.
5. Evaluate the generated summaries and iterate on the prompt if needed.

By mastering these core machine learning and AI concepts, you'll be well-prepared for the NVIDIA Certified AI Associate (NCA) certification and ready to tackle real-world AI applications.
