This report synthesises findings from 7 peer-reviewed papers addressing the following research question: How do mixed-data-type generative models perform in preserving statistical dependencies under high-sparsity conditions as measured by downstream task accuracy on TabularMIPT. 7 claims were extracted from source literature; 7 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 7.6/10. This report is a machine-generated literature synthesis and does not constitute original research.Research goal: How do mixed-data-type generative models perform in preserving statistical dependencies under high-sparsity conditions as measured by downstream task accuracy on TabularMIPT?Autonomous literature synthesis.
