Query/Prompt Reformulation is Magic

There was an interesting study done earlier this year called What’s the Magic Word? A CONTROL THEORY OF LLM PROMPTING.

The study applied control theory to prompt engineering in Large Language Models (LLMs), demonstrating that short prompts can significantly influence the output, thus providing a foundational understanding of LLM controllability or what they termed "Magic Words".

Summary and Overview of the Study

This research attempts to address how to mathematically formalize prompt engineering for large language models (LLMs) through the lens of control theory (a fundamentally flawed endeavour but that's for another time).

From a practical aspect, the study is fundamentally about prompt optimization. The goal is to understand and improve how prompts (or input sequences) can be engineered to effectively control the outputs of large language models (LLMs).

1. Key Findings:
   • Reachability: The research finds that with prompts of 10 tokens or fewer, the correct next Wikitext token is reachable over 97% of the time, using "magic words."
   • Token Likelihood: The top 75 most likely next tokens are reachable at least 85% of the time with short prompts. Additionally, short prompts can significantly alter the probabilities of specific outputs, making less likely tokens become more likely.
2. Key Points About "Magic Words":
   1. Context-Dependent: The specific "magic words" or optimal prompts will vary based on the initial state sequence and the desired outcome. What works well in one context might not be effective in another.
   2. Prompt Optimization: Finding these "magic words" involves optimizing the prompts through techniques that can iteratively adjust and test different token sequences to see which ones yield the best results.
3. Practical Implications:
   1. Task-Specific Prompts: For tasks such as knowledge retrieval, reasoning, and sentiment analysis, the "magic words" will be tailored to the specific requirements of these tasks.
   2. Iterative Improvement: By using prompt optimization algorithms, one can iteratively find and refine these prompts to improve the performance of LLMs on specific tasks.
4. Example:
   1. For a task like generating the continuation of a story, the "magic words" might include specific phrases that set the scene or introduce characters in a way that guides the LLM to generate a coherent continuation.
   2. For sentiment analysis, the prompt might include context-setting words that make it clear the sentence to be analyzed is about expressing emotions.

So What are the ACTUAL "Magic Words"

Well the researchers never really say what are the "magic words." When you go through the paper, there are actually NO Magic Words. (Surprised?)

You see, according to the paper, "magic words" are not specific, fixed phrases but rather vary depending on the output you are trying to achieve from the large language model (LLM). How do you find these "Magic Words"?

High Level Overview of Finding "Magic Words"

So according to the paper, "magic words" are derived from prompt optimisation of the specific prompt for the specific use case.

I'm not going to go into the process in depth but here's the overview.

Of course in the paper, like all other research, the tests were all automated and while they give a handful of examples, the bulk of the output validation are evaluated programatically using heuristics. Which when dealing with LLMs are not suitable.

So what is prompt optimisation according to the researchers? When you dig into the paper, you realise prompt optimisation is our old friend Query/Task Reformulation.

Incorporating a specialized LLM agent for query reformulation provides numerous benefits, including enhanced security, improved contextual understanding, consistency, resource efficiency, and a better user experience. By addressing potential security issues such as prompt injections and optimizing the processing of user queries, this approach not only bolsters the robustness and reliability of AI systems but also ensures their scalability and adaptability to evolving user requirements and diverse domains.

Preference for Query Reformulation over Repeated User Prompts

In many conversational AI scenarios, particularly within specialized domains where time efficiency is critical, query reformulation offers distinct advantages over constantly asking the user to clarify or repeat their questions. This approach not only enhances user experience but also improves the overall efficiency and effectiveness of the interaction.

1. Enhanced User Experience

• Reduction in User Frustration: Constantly asking the user to clarify or repeat their queries can lead to frustration and a negative user experience. Query reformulation alleviates this issue by transforming the original query into a clearer, more detailed version without requiring additional input from the user.
• Seamless Interaction: By automatically refining and enhancing the user's query, the AI system can maintain a smooth and uninterrupted flow of conversation. This seamless interaction is particularly important in domains where the continuity of information exchange is crucial, such as customer support or telemedicine.

2. Time Efficiency

• Critical in Time-Sensitive Domains: In fields like healthcare, emergency response, or financial trading, every second counts. Query reformulation can quickly refine user queries to ensure precise and relevant responses without the delays caused by back-and-forth clarifications.
• Speedier Resolutions: By directly providing the AI with a well-structured query, the system can generate accurate responses more quickly, leading to faster problem resolution and decision-making.

3. Improved Accuracy and Contextual Understanding

• Context Retention: In a conversational scenario, maintaining context is key. Query reformulation helps retain and build upon the context of previous interactions, reducing the chances of misinterpretation that could occur if the user has to rephrase their query repeatedly.
• Detailed Responses: Reformulated queries often include additional context and specificity, enabling the AI to deliver more accurate and comprehensive responses. This is especially important in technical fields where detailed information is necessary.

4. Reduced Cognitive Load on Users

• Simplified User Interaction: Users are not always adept at framing their questions in a way that an AI system can easily understand. Query reformulation simplifies user interaction by automatically refining their input, reducing the cognitive load on the user and making the AI more accessible.
• Enhanced Accessibility: For users who may have difficulty with language or who are in high-stress situations, minimizing the need for repeated input makes the system more user-friendly and accessible.

5. Consistency and Standardization

• Uniform Query Format: Query reformulation can standardize user inputs into a consistent format, ensuring that the AI system processes each query uniformly. This standardization improves the reliability of the responses and helps maintain high-quality interactions.
• Domain-Specific Adaptations: The reformulation process can tailor queries to fit the specific requirements and terminologies of different domains, enhancing the accuracy and relevance of the AI's responses.

6. Case Example: Healthcare

• Scenario: In a telemedicine consultation, a patient might initially ask, "What can I do about my headache?"
• Reformulated Query: The AI could reformulate this to, "Could you provide a detailed explanation of potential treatments and home remedies for a persistent headache, including when it is necessary to seek immediate medical attention?"
• Benefit: This reformulation provides the healthcare professional with a clearer understanding of the patient's needs, leading to a more precise and informative response, all without the patient needing to rephrase or provide additional context.

Query reformulation is a preferred strategy over repeatedly prompting the user for clarification, especially in time-sensitive and specialized domains. By enhancing user experience, improving time efficiency, retaining context, reducing cognitive load, and ensuring consistency, query reformulation makes conversational AI interactions more effective and user-friendly. This approach not only facilitates faster and more accurate responses but also supports a seamless and positive user experience, which is crucial in scenarios where every moment and detail matters.

Query reformulation is a powerful technique that can significantly enhance the effectiveness of interactions with conversational AI systems like ChatGPT or Claude. By refining and clarifying user queries, reformulation helps these systems provide more accurate and relevant responses. Here are some key points on how query reformulation can be leveraged:
