Researchers have developed a method to transfer information between independently trained health foundation models by aligning their data-dependent coordinate systems. This approach extracts symbol-like components from frozen embeddings using linear decomposition and aligns them across models with simple linear maps. These aligned symbols show selective associations with health conditions and physiological attributes, demonstrating similar patterns across different modalities and architectures. A classifier trained on symbols from one model retains over 95% of its performance when applied to another, indicating that these health models converge on a common representation of underlying physiology.
