מושגי ליבה
PROMPT-SAW, a novel framework that leverages graph structures to extract key information elements from prompts, enabling effective compression while preserving semantic coherence and end-task performance.
תקציר
The paper proposes PROMPT-SAW, a novel framework for compressing textual prompts used in large language models (LLMs). Unlike existing token-level compression approaches, PROMPT-SAW leverages the inherent graph structure of prompts to identify and retain key information elements, leading to compressed prompts that are more readable and maintain end-task performance.
The key highlights are:
-
PROMPT-SAW constructs a graph representation of the prompt text, where entities and their relations are captured as nodes and edges respectively. This graph structure enables PROMPT-SAW to analyze the prompt at a more granular level compared to token-level approaches.
-
For task-aware prompts, PROMPT-SAW selectively retains only the task-specific information elements in the graph. For task-agnostic prompts, it identifies and removes redundant information elements based on their similarity scores.
-
The compressed prompts generated by PROMPT-SAW exhibit better readability and grammatical coherence compared to existing baselines, as validated by both qualitative examples and quantitative fluency scores.
-
Extensive experiments on benchmark datasets show that PROMPT-SAW outperforms state-of-the-art baselines by up to 14.3% and 13.7% in task-aware and task-agnostic settings respectively, while compressing the original prompt by 33.0% and 56.7%.
-
The authors also propose GSM8K-AUG, an extended version of the existing GSM8K benchmark, to provide a more comprehensive evaluation platform for task-agnostic prompt compression.
Overall, PROMPT-SAW presents a novel and effective approach to prompt compression that preserves the semantic coherence and end-task utility of the compressed prompts.

How can the graph-based approach of PROMPT-SAW be extended to other types of structured data beyond textual prompts?
PROMPT-SAW's graph-based approach can be extended to other types of structured data beyond textual prompts by adapting the methodology to suit the specific characteristics of the data. For example:
Tabular Data: In the case of tabular data, entities can represent columns or rows, while relations can signify the relationships between them. By constructing a graph where nodes represent different attributes and edges represent connections or dependencies, PROMPT-SAW can identify key information elements and compress the data effectively.
Image Data: For image data, entities can represent objects or features within the image, while relations can indicate spatial relationships or visual connections. By creating a graph structure based on these entities and relations, PROMPT-SAW can extract essential visual elements and compress the image data while maintaining its semantic integrity.
Knowledge Graphs: In scenarios where structured knowledge graphs are available, PROMPT-SAW can leverage the existing graph structure to identify key entities and relationships. By applying similar graph-based compression techniques, it can reduce redundancy and optimize the knowledge graph for specific tasks or applications.
By adapting the graph-based approach of PROMPT-SAW to different types of structured data, it can effectively identify and extract essential information elements while reducing the overall complexity and size of the data, leading to improved efficiency and performance in various applications.
What are the potential limitations of the similarity-based redundancy removal approach used by PROMPT-SAW for task-agnostic prompts, and how could it be further improved?
One potential limitation of the similarity-based redundancy removal approach used by PROMPT-SAW for task-agnostic prompts is the sensitivity to the threshold parameter δ. Setting the threshold too high may result in the removal of important information elements, leading to loss of critical details in the compressed prompt. On the other hand, setting the threshold too low may retain redundant information, reducing the effectiveness of the compression.
To address this limitation and improve the approach, several strategies can be considered:
Dynamic Threshold Adjustment: Implementing a dynamic threshold adjustment mechanism that adapts the similarity threshold based on the characteristics of the data and the specific task requirements. This adaptive approach can ensure optimal redundancy removal without sacrificing essential information.
Multi-level Similarity Analysis: Instead of relying on a single similarity threshold, PROMPT-SAW could incorporate multi-level similarity analysis. By considering different levels of similarity between information elements, the model can prioritize the retention of more distinct and relevant elements while filtering out highly redundant ones.
Contextual Information Integration: Incorporating contextual information and semantic relationships between information elements can enhance the redundancy removal process. By considering the context in which the information elements appear, PROMPT-SAW can better differentiate between essential and redundant elements for compression.
By implementing these enhancements, PROMPT-SAW can overcome the limitations of the similarity-based redundancy removal approach and achieve more precise and effective prompt compression for task-agnostic scenarios.
Given the importance of prompt engineering for LLMs, how could PROMPT-SAW's techniques be integrated into a broader framework for interactive prompt design and optimization?
PROMPT-SAW's techniques can be integrated into a broader framework for interactive prompt design and optimization by incorporating the following strategies:
Interactive Prompt Generation: Implementing an interactive interface where users can provide feedback on the compressed prompts generated by PROMPT-SAW. This feedback loop can help refine the compression process and tailor the prompts to specific user preferences or task requirements.
Prompt Customization Modules: Developing modules that allow users to customize the compression parameters, such as the target compression rate or the importance of different information elements. This customization feature can empower users to fine-tune the prompt compression process according to their needs.
Prompt Evaluation Metrics: Introducing comprehensive evaluation metrics that assess the quality, readability, and utility of the compressed prompts generated by PROMPT-SAW. By incorporating user-centric metrics, the framework can ensure that the compressed prompts meet the desired criteria for effective interaction with LLMs.
Prompt Optimization Algorithms: Integrating optimization algorithms that automatically adjust the compression parameters based on real-time performance feedback. This adaptive approach can continuously optimize the prompt design process and enhance the overall efficiency of prompt engineering for LLMs.
By integrating these components into a broader framework, PROMPT-SAW's techniques can be leveraged for interactive prompt design and optimization, enabling users to create tailored prompts that enhance the performance and usability of LLMs in various applications.
