New framework TaNOS boosts AI numerical reasoning on tables

By PulseAugur Editorial · [1 sources] ·

Researchers have developed TaNOS, a new framework designed to improve numerical reasoning in AI models when dealing with complex, domain-specific tables. The framework uses header anonymization, operation sketches for structural cues, and self-supervised pretraining to construct program-question pairs. This approach helps models generalize better across different domains, reducing reliance on superficial shortcuts. When applied to an 8B instruction-tuned model, TaNOS achieved significant improvements in accuracy and robustness, outperforming proprietary models like GPT-5 and Gemini 2.5 Pro on the FinQA dataset.

    Generalizing Numerical Reasoning in Table Data through Operation Sketches and Self-Supervised Learning

    arXiv:2604.21495v2 Announce Type: replace-cross Abstract: Numerical reasoning over expert-domain tables often exhibits high in-domain accuracy but limited robustness to domain shift. Models trained with supervised fine-tuning (SFT) on specific datasets tend to rely on header-oper…
