Safe Intelligence - this forms the core brand of the Fraunhofer Institute for Cognitive Systems IKS. Connected cognitive systems drive innovation in many sectors, including mobility, healthcare, and automation in industry. Disruptive technologies such as artificial intelligence and quantum computing play a key role here. Fraunhofer IKS is conducting research to ensure that these applications are reliable and verifiably safe. We consider resilience and intelligence to be part of the same process.

What you will do

Generative AI opens up new possibilities for the automatic creation of structured text (ST) for PLCs. Although LLMs can already generate functional ST code from natural language requirements, the quality of the result is often insufficient. An automated feedback loop that analyzes the code, converts errors into appropriate correction feedback, and feeds it back to the LLM promises significant improvements in this area. The aim of this master's thesis is to systematically evaluate the functionality of such an automated feedback loop for the first time.

Tasks:

• Systematic literature analysis on feedback mechanisms and quality metrics for LLM-based code generation.
• Identification of relevant metrics and tests (static/dynamic) that best reflect the code quality and functional safety of ST.
• Determination of the optimal format for transferring the metrics and test results to the LLM.
• Development of a prototype software module that automatically generates feedback in the defined format from the selected metrics and tests.
• Quantitative and qualitative evaluation of the feedback process by measuring the code improvements achieved through the feedback and comparing them with a baseline.

What you bring to the table

• Currently pursuing a degree in engineering, with a focus on informatics or AI
• Good knowledge in programming with python and on software development
• Knowledge on LLMs and langchain is a plus
• Analytical and structured mindset
• Good knowledge of the English and German language (B2).

What you can expect

• Participation in a dynamic team with innovative task areas and nice supervisors.
• Practical approach to your studies
• Excelent support for your thesis
• Collaboration on practical research projects.
