Problem statement
Context
Large Language Models (LLM) can serve many useful purposes for large enterprises by enabling easy and approachable access to large sets of data and provide higher efficiency in product development. Bosch already has AI based tooling to support our software developers and we explore new methods to optimize our supporting tools.
Problem
The results from the LLM however can be inaccurate meaning it can sometimes provide incorrect answers to questions or is unable to correctly interpret the question or task. The LLM can also produce results that are made up of nonexisting data socalled hallucinations. These issues can have severe impact on the application/developers that rely on them making them unreliable and invalid for production level solutions.
Proposed solution
One approach to improve accuracy and reduce hallucinations is to enhance the LLM by storing the underlying data in a knowledge graph. The knowledge graph provides semantics and context to the data clearly labeling the data points and the relations between them. This makes it easier for the LLM to draw the correct conclusions from the data because of how the knowledge graph structures the data. The solution would be implemented as a proof of concept and evaluated based on the performance regarding accuracy and hallucinations. The solution shall be tested in an existing LLM based Bosch LogAnalyzer tooling.
Goal of the Master Thesis:
To implement a proofofconcept for a Graph RAG LLM identify how to evaluate the accuracy and hallucinations and evaluate the performance of various queries.
Suggested approach:
- Implement the GraphRAG with use of an existing LLM
- The LLM should be extended with a GraphRAG implementation
- As data source for development GraphRAG an opensource dataset should be used
- Validation shall be done with Bosch LogAnalyzer tooling
For example; use of NASA Open Data Portal (various open data sources provided by NASA) logpai/loghub (a large collection of system log datasets for AIdriven log analytics)
You will of course have the opportunity to shape the thesis based on your knowledge skills and discoveries during the project.
