This report synthesises findings from 3 peer-reviewed papers addressing the following research question: How does the sample complexity of CausalMixFT-scale synthetic data generation affect the convergence rate and final accuracy of fine-tuned tabular foundation models compared to standard mixing. 9 claims were extracted from source literature; 9 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 9.0/10. This report is a machine-generated literature synthesis and does not constitute original research.Research goal: How does the sample complexity of CausalMixFT-scale synthetic data generation affect the convergence rate and final accuracy of fine-tuned tabular foundation models compared to standard mixing strategies?Autonomous literature synthesis.
