Using Nomadic To Optimize a Compound AI System for Summarization

A compound AI system leverages a sequence of interconnected stages to refine data flow and maximize AI performance, specifically tailored for summarization tasks. Each phase builds on the work of the previous one, passing critical information forward to ensure accuracy and consistency in generating concise summaries.

Part 1: System Prompt Optimization

  • Goal: Fine-tune prompts to guide AI behavior in producing effective summaries.
  • Importance: The optimal prompt crafted here is directly used in both Part 2 (retrieval) and Part 3 (inference), setting the tone for how the AI interprets and summarizes the input data.

Part 2: Retrieval Experiment

  • Goal: Retrieve the most relevant information using advanced search techniques to support accurate summarization.
  • Importance: The system prompt from Part 1 drives this process, and the retrieved data is passed to Part 3, forming a rich knowledge base that the AI relies on to generate precise and relevant summaries.

Part 3: Inference Experiment

  • Goal: Generate high-quality summaries using the most relevant data retrieved.
  • Importance: Combines the optimized prompt from Part 1 with the precise retrieval results from Part 2 to ensure that AI-generated summaries are contextually accurate and grounded in solid information.

Part 4: Reinforcement Learning Agent (RLAgent)

  • Goal: Continuously refine the AI’s decision-making process to improve summary quality.
  • Importance: Uses insights from the inference phase (Part 3) to learn and adapt, closing the loop and feeding improvements back into the system for more effective summarization over time.

Critical Data Flow

  1. Optimized prompt from Part 1 → Guides retrieval strategies in Part 2 and shapes AI responses in Part 3 for summarization.
  2. Retrieval results from Part 2 → Directly influence the summary generation in Part 3 and fine-tune learning processes in Part 4.

This streamlined flow ensures that every component enhances the next, creating a system that evolves intelligently, delivering ever more precise and contextually relevant summaries.

RAG (Retrieval-Augmented Generation) Pipeline in Nomadic

Nomadic's RAG pipeline enhances AI model performance by integrating external documents to generate accurate, contextually relevant responses. The process begins by obtaining RAG inputs, where documents, evaluation questions, and reference responses are extracted from specified sources.

Next, the Retrieval Experiment is conducted using Nomadic's Experiment framework. Here, various parameters like top_k, model_name, and retrieval_strategy are optimized to select the most relevant documents. Results are saved and the best retrieval configuration is identified for subsequent use.

Following retrieval, the Inference Experiment generates responses based on the retrieved documents. Parameters such as similarity_threshold and reranking_model are tuned to ensure high-quality outputs.

This seamless integration within Nomadic allows for enhanced accuracy, scalability, and continuous improvement of AI responses. By leveraging optimized retrieval and inference processes, Nomadic ensures its AI models deliver reliable and contextually appropriate information across diverse applications.

Reinforcement Learning Optimization in Nomadic

Phase 1: Prompt Tuning and RAG

In Phase 1, Nomadic enhanced its optimization pipeline through:

  • Prompt Tuning: Refined input prompts to improve response relevance and accuracy.
  • Retrieval-Augmented Generation (RAG): Integrated external data sources to enrich generated content with up-to-date information.

Phase 2: Robustness Testing with Reinforcement Learning

Building on Phase 1, Phase 2 assesses the resilience of the optimized Prompt + RAG configuration against jailbreaking attempts. This phase utilizes an RL Agent to ensure system integrity:

  • Adaptive Defense Strategies: RL agents dynamically adjust defenses based on real-time threat detection.
  • Continuous Learning: Agents improve their strategies through ongoing interactions and feedback.
  • Comprehensive Evaluation: Simulated adversarial scenarios test and strengthen the Prompt + RAG pipeline’s robustness.

Optimization Through Hyperparameter Tuning

To maximize the RL agent's effectiveness, Nomadic employs hyperparameter tuning:

  • Learning Rate & Discount Factor: Fine-tuned to balance convergence speed and long-term strategy planning.
  • Model Architecture: Optimized neural network configurations enhance learning capacity and adaptability.
  • Reward Function Design: Engineered to prioritize accurate threat detection and system resilience.

Conclusion

Phase 2 leverages Reinforcement Learning Optimization to validate and fortify Nomadic’s Prompt + RAG pipeline against sophisticated jailbreaking threats. Through strategic hyperparameter tuning, Nomadic ensures its optimization platform remains secure, adaptive, and highly performant across diverse applications.
