We are seeking a motivated student for a master thesis in LLM-based Automated Root-Cause Analysis for the automotive industry. You will develop methods to analyze extensive textual data from multiple sources. You will work on prompt engineering and fine-tuning of large language models, in collaboration with industry experts. The objective of the thesis is to learn the dependency between observations in the time-series data and the correlations with the physical system, to finally rank the potential failure modes, and to cluster similar failure conditions. The thesis will offer valuable insights into addressing root causes of issues of powertrain systems. YOUR RESPONSIBILITIES: Gather from various sources (e.g., FP-sheets, technical reports, presentations, word documents) to create a knowledge database. Define the database structure for efficient processing of textual data. Apply simple analytics to detect deviations from the expected behavior or use existing analysis results. Assign appropriate textual descriptions to the observations (e.g., very high battery cell temperature, low pack voltage, normal contactor temperature, etc.). Apply a wide range of techniques (e.g., few-shot classification, RAGs, Chain-Of-Thoughts) from the field of LLMs to learn the dependency between observations and the knowledge database content. Provide a ranking of the top potential failure modes along with their probabilities for a specific combination of observed conditions. Cluster similar observed conditions related to different failure modes in the knowledge database. Define a validation approach with the appropriate metrics from the literature and validate the outcome of the analysis.
