GOTabPFN: From Feature Ordering to Compact Tokenization for Tabular Foundation Models on High-Dimensional Data
arXiv:2606.05441v1 Announce Type: new Abstract: We investigate how to make small tabular foundation models effective for High-Dimensional, Low-Sample Size (HDLSS) tabular prediction without retraining large backbones. We introduce Graph-guided Ordering with Local Refinement (GO-LR), show its equivalence to weighted Minimum Linear Arrangement, and interpret the practical solver as a TSP-path-style surrogate. We propose GOTabPFN,which builds on GO-LR, and a Neuro-Inspired Subunit Compression (NSC) unit to pool locally adjacent ordered features into meta-features, yielding a compact representatio
The proliferation of high-dimensional, low-sample size datasets necessitates more efficient and compact tabular foundation models to maintain performance without extensive retraining.
This development proposes a method to create effective small tabular foundation models, making advanced AI techniques more accessible and computationally lighter, particularly for resource-constrained environments or specialized data sets.
The ability to achieve strong performance with smaller tabular foundation models and compact tokenization allows for more efficient deployment and less reliance on massive computational resources for certain AI tasks.
