Two new research papers delve into the intricacies of tabular foundation models (TFMs), exploring their performance and ensemble strategies. The first paper provides a mechanistic study, analyzing how different TFM architectures converge in accuracy and identifying their specific inductive biases and failure modes. The second paper investigates ensembling techniques for TFMs, revealing a diversity ceiling and a calibration trap where combining models can yield diminishing returns and even degrade performance.
