The use of artificial intelligence (AI) and machine learning (ML) in archaeology has rapidly gained momentum due to its potential to automate and enhance the efficiency of data analysis. This paper examines the application of neural networks for processing Digital Terrain Model (DTM) data to detect archaeological sites in Poland. The study focuses on identifying trenches, mounds, and charcoal kilns through automated image segmentation, utilizing a U-Net convolutional neural network. While the results demonstrate the promise of AI in improving archaeological site detection, various challenges are highlighted, including data quality, feature misclassification, and regional variability in model performance. Additionally, the research underscores the need for interdisciplinary collaboration, as successful implementation requires expertise in archaeology, geospatial analysis, and programming. Despite AI’s potential for time-saving, significant effort is required to ensure accurate annotations and avoid over-reliance on the technology. The case study provides valuable insights into the complexities of applying AI to large-scale archaeological datasets and raises important questions about the limitations and future development of these methods. This paper concludes that while AI offers powerful tools for archaeological research, careful consideration must be given to its methodological challenges. Standardizing procedures and improving data quality will be critical to fully exploiting AI's potential in archaeology.
