RAG Works Pipeline

Posted on by lechuck park

This image illustrates the RAG (Retrieval-Augmented Generation) Works Pipeline, breaking down the complex data processing workflow into five intuitive steps using relatable analogies like cooking and organizing.

Here is a step-by-step breakdown of the pipeline:

  • Step 1: Preprocessing (“preparing the ingredients”)
    Just like prepping ingredients for a meal, this step filters raw, unstructured data from various formats (PDFs, HTML, tables) through a funnel to extract clean text. By handling noise removal, format standardization, and text cleansing, it establishes a solid data foundation that ultimately prevents AI hallucinations.
  • Step 2: Chunking (“cutting into bite-sized pieces”)
    Long documents are sliced into smaller, manageable pieces that the AI model can easily process. Techniques like semantic splitting and overlapping ensure that the original context is preserved without exceeding the AI’s token limits. This careful division drastically improves the system’s overall search precision.
  • Step 3: Embedding (“translating into number coordinates”)
    Here, the text chunks are converted into mathematical vectors mapped in a high-dimensional space (X, Y, Z axes). This vectorization captures the underlying semantic meaning and context of the text, allowing the system to go beyond simple keyword matching and achieve true intent recognition.
  • Step 4: Vector DB Storage (“stocking the AI’s specialized library”)
    The embedded vectors are systematically stored and indexed in a Vector Database. Think of it as a highly organized, specialized filing cabinet designed specifically for AI. Efficient indexing allows for high-dimensional searches, ensuring optimal speed and scalability even as the dataset grows massively.
  • Step 5: Search Optimization (“picking the absolute best matches”)
    Acting as a magnifying glass, this final step identifies and retrieves the most relevant information to answer a user’s query. Using advanced methods like cosine similarity, hybrid search, and reranking, the system pinpoints the exact data needed. This precise retrieval guarantees the highest final output quality for the AI’s generated response.

Events with RAG(LLM)

Posted on by lechuck park

Step 1: Event Detection & Ingestion

This initial stage focuses on capturing system anomalies through real-time monitoring, collecting necessary logs, and extracting essential metadata to understand the context of the event.

Step 2: RCA: Root Cause Analysis

It identifies the fundamental issue behind the surface-level symptoms by utilizing correlation analysis, distributed tracing, root cause drill-down, and infrastructure topology analysis.

Step 3: Query Formulation for RAG

The system translates the RCA findings into an optimized search prompt through query reformulation, entity extraction, and intent classification to fetch the most accurate solutions.

Step 4: Retrieval

It searches for the most relevant technical documents or past incident records from a Vector Database, leveraging hybrid search, chunking strategies, and document re-ranking techniques.

Step 5: Generation via LLM

The LLM generates an actionable troubleshooting guide by combining prompt engineering and context injection, strictly mitigating any AI hallucinations.

Step 6: Action & Knowledge Update

Finally, after the issue is resolved, the system automatically updates its knowledge base with post-mortem reports, ensuring a continuous feedback loop through an automated LLMOps pipeline.

Summary

  1. Event Detection & Root Cause Analysis: When a system incident occurs, it is captured in real-time, and the system deeply traces the actual root cause rather than just addressing surface-level symptoms.
  2. Knowledge Retrieval & Solution Generation: The analyzed root cause is transformed into a RAG-optimized query to retrieve the best reference documents from the internal knowledge base, allowing the LLM to generate an immediately actionable troubleshooting guide.
  3. Knowledge Capitalization & Virtuous Cycle: Once the issue is resolved, a post-mortem report is generated and automatically fed back into the knowledge base, creating a continuously evolving and automated pipeline.
