Researchers have developed Tydra, a novel hybrid model that combines Transformer and State Space Model (SSM) architectures to improve efficiency in tabular data in-context learning. This new architecture interleaves attention and SSM layers, addressing the quadratic computational cost of pure Transformer models like TabPFN while maintaining strong predictive performance. Evaluations on 30 OpenML datasets show Tydra achieves a 30% reduction in inference time compared to TabPFN and outperforms a significantly larger Hydra model, indicating that hybrid approaches are a promising avenue for tabular foundation models.
