Cross-species transferability of an ultrastructure-to-dynamics compiler

Determine whether an ultrastructure-to-dynamics compiler trained on data from one species can transfer with high predictive accuracy to another species.

Background

Domain shift across species is a core risk for learned mappings from structure to dynamics. Even if many molecular functions are conserved, structural and physiological differences may hinder transfer.

Establishing whether and when a compiler trained in one species generalizes to another is essential for broad applicability and avoids overfitting to species-specific features.

References

Although many molecular functions are conserved across species, it remains unclear whether a compiler trained in one species would transfer well to another.
