LimiX-2: A Contextual Mechanism Network Towards General Structured-Data Intelligence
Stable AI
LimiX-2 scales a Contextual Mechanism Network pretrained with context-conditional masked modeling on synthetic structural-causal-model data, shifting from target-centric prediction to mechanism-oriented joint modeling of p(x, y | D_context). It outperforms dataset-specific models and existing tabular foundation models on TabArena, TALENT and BCCO, and its feature attention recovers causal skeletons.
