KnowsTFM: Knowledge-Informed Fine-Tuning of Small Tabular Foundation Models

Boshko Koloski, Xiangjian Jiang, Senja Pollak +3

Tabular foundation models have advanced deep learning for tabular data by delivering strong default performance across many small and medium tasks. Yet in niche domains, where data…

Tabular Foundation Model for Generative Modelling

Xiangjian Jiang, Mingxuan Liu, Nikola Simidjievski +2

Generative modelling is a demanding test of foundation models, because it requires robust, holistic representation learning for a given data modality, rather than optimisation for…

TabStruct: Measuring Structural Fidelity of Tabular Data

Xiangjian Jiang, Nikola Simidjievski, Mateja Jamnik

Evaluating tabular generators remains a challenging problem, as the unique causal structural prior of heterogeneous tabular data does not lend itself to intuitive human inspection.…

RO-FIGS: Efficient and Expressive Tree-Based Ensembles for Tabular Data

Urška Matjašec, Nikola Simidjievski, Mateja Jamnik

Tree-based models are often robust to uninformative features and can accurately capture non-smooth, complex decision boundaries. Consequently, they often outperform neural network-…
