arXiv:2606.09257v1 Announce Type: new Abstract: High-Dimensional Low-Sample Size (HDLSS) tabular domains (e.g., omics) are characterized by $n \ll m$, where $n$ = number of samples, and $m$ = number of features. Such domains often exhibit strong local correlation groups, sparse cross-group dependencies, heavy-tailed non-Gaussian marginals, heteroscedastic noise, and structured missingness, making direct density learning in $\mathbb{R}^m$ ill-conditioned since $n \ll m$. We propose BSTabDiff, a block-subunit generative framework that partitions the $m$ observed features into $M$ latent blocks (
The increasing complexity and dimensionality of real-world tabular datasets, especially in fields like omics, are driving demand for more robust generative models that can handle their unique statistical challenges.
This development proposes a new method for generating high-dimensional tabular data, which could improve synthetic data generation, privacy-preserving data sharing, and the development of more accurate AI models for complex datasets where real data is scarce.
The ability to generate more realistic and statistically sound high-dimensional tabular data will improve model training and potentially enable new applications in fields characterized by limited samples and many features.
