TabICLv2: A better, faster, scalable, and open tabular foundation model

TabICLv2 is a new state‑of‑the‑art tabular foundation model that outperforms existing methods on regression and classification tasks. It relies on a synthetic data generation engine for diverse pretraining, architectural innovations such as a scalable softmax attention, and optimized training protocols that replace AdamW with the Muon optimizer. On the TabArena and TALENT benchmarks, TabICLv2 surpasses the current best model, RealTabPFN‑2.5, without any tuning, while also being faster and capable of handling million‑scale datasets with limited GPU memory.

Solving In-Table Prediction Problems by Deep Neural Networks with Performance Evaluation Using Synthetic Data

The paper introduces In-Table Prediction (ITB), a self‑supervised task where deep neural networks learn to predict any column in a table from the remaining columns. It proposes a novel neural layer to handle missing continuous values, generates synthetic datasets with controlled column relationships, and evaluates three architectures—MLP, ResNet, and Transformer—showing that attention‑based Transformers perform best when ample training data and large embeddings are used. The study is limited to synthetic, small‑column tables and is presented as an initial investigation rather than a comprehensive real‑world analysis.

TabNSM: Neural Sparse Mixer for Tabular Regression

TabNSM is a scalable regression framework for large-scale, high-dimensional tabular data that builds on sparse-attention and mixer architectures. Its core component, the Adaptive Sparse Interaction Module (ASIM), combines foreground feature discovery, sparse local interaction encoding, and Feature-Token Mixing to achieve near-linear complexity. For regression, TabNSM adds a Multi-Stage Regression Head, GridLoss (an ordinal-aware soft-binning objective), and RISE (a difficulty-aware sampling strategy), achieving strong predictive performance and practical scalability across nine real-world benchmarks, especially on high-dimensional and heterogeneous datasets.
