Session 2: Prompt Engineering

Prompt engineering is a critical discipline in the field of Artificial Intelligence (AI), particularly for generative AI models like Large Language Models (LLMs) and image generators. It involves crafting and refining prompts to elicit specific, useful responses from these models. Here’s a detailed overview:

What is Prompt Engineering?

  • Definition: Prompt engineering is the process of designing and optimizing prompts—questions or instructions—to guide AI models, especially generative AI, towards producing desired outputs. It acts as the interface between human intent and machine output12.
  • Purpose: The goal is to ensure that AI systems, such as chatbots or image generators, provide accurate and relevant responses by carefully structuring the input prompts34.

Techniques in Prompt Engineering

1. Zero-Shot Prompting

  • Definition: This technique involves providing a prompt without any examples or prior context, relying on the model’s understanding based on its training data.
  • Use Case: Ideal for simple tasks or when examples are not necessary32.

2. One-Shot Prompting

  • Definition: Involves providing a single example or piece of context to guide the model’s response.
  • Use Case: Useful for tasks where a single example can help the model understand the desired output2.

3. Few-Shot Prompting

  • Definition: Provides multiple examples within the prompt to help the model learn in context.
  • Use Case: Effective for more complex tasks where multiple examples are needed for accurate responses3.

4. Chain-of-Thought Prompting

  • Definition: Breaks down complex questions into smaller, logical parts to mimic a train of thought.
  • Use Case: Enhances reasoning abilities by solving problems in intermediate steps12.

5. Tree-of-Thought Prompting

  • Definition: Generalizes chain-of-thought prompting by generating multiple possible next steps.
  • Use Case: Useful for exploring different paths to a solution1.

6. Maieutic Prompting

  • Definition: Involves prompting the model to answer a question with an explanation and then explaining parts of the explanation.
  • Use Case: Improves performance on complex commonsense reasoning tasks1.

7. Complexity-Based Prompting

  • Definition: Chooses the most complex chain-of-thought rollouts to select the final answer.
  • Use Case: Effective for complex problems requiring multiple steps1.

8. Generated Knowledge Prompting

  • Definition: Involves prompting the model to generate relevant facts before completing the task.
  • Use Case: Enhances completion quality by conditioning on relevant facts1.

9. Least-to-Most Prompting

  • Definition: Lists subproblems and solves them sequentially.
  • Use Case: Ensures that later subproblems can be solved with the help of previous answers1.

10. Self-Refine Prompting

  • Definition: Involves critiquing the model’s solution and refining it iteratively.
  • Use Case: Improves the quality of responses through continuous refinement1.

11. Iterative Prompting

  • Definition: Builds upon previous responses by asking follow-up questions.
  • Use Case: Useful for gathering detailed information or clarifying ambiguities2.

12. Directional-Stimulus Prompting

  • Definition: Includes hints or cues to guide the model towards the desired output.
  • Use Case: Effective for creative tasks like writing or art generation1.

13. Prompt Combination

  • Definition: Combines multiple instructions or questions into a single prompt.
  • Use Case: Elicits comprehensive answers by addressing multiple aspects of a topic2.

14. Target-Your-Response (TAYOR) Prompting

  • Definition: Specifies the desired look-and-feel of the generated content.
  • Use Case: Ensures that the output aligns with specific stylistic or thematic requirements6.

15. Information Retrieval Prompting

  • Definition: Treats LLMs as search engines to retrieve specific information.
  • Use Case: Ideal for tasks requiring detailed or up-to-date information2.

These techniques help optimize interactions with AI models, ensuring that they produce accurate and relevant outputs.
