Evaluating latent knowledge of public tabular datasets in large language models to detect data contamination

advanced Published 31 Mar 2026
Action Steps
  1. Identify public tabular datasets used in training large language models
  2. Develop a framework to assess contamination in these datasets
  3. Use memorization tests as a baseline for comparison
  4. Propose a new approach to detect contamination beyond memorization tests
Who Needs to Know This

Data scientists and AI engineers on a team can benefit from this research to improve the generalization of large language models and detect potential data contamination, which is crucial for reliable model performance

Key Insight

💡 Existing approaches to detect data contamination in tabular datasets are too coarse and a new framework is needed to assess latent knowledge in large language models
