Fine-Tuning Large Language Models for Digital Forensics: Case Study and General Recommendations

Gaƫtan Michelet; Hans Henseler; Harm van Beek; Mark Scanlon; Frank Breitinger

ACM Digital Threats: Research and Practice pp. 3748264

This paper proposes recommendations for fine-tuning large language models (LLMs) for digital forensics tasks, addressing the gap in existing research. A case study on chat summarization showcases the applicability of the recommendations, evaluating multiple fine-tuned models to assess their performance. The study shares lessons learned from the case study, providing insights into the fine-tuning process, computational power issues, data challenges, and evaluation methods.
