The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

SPIN improves real-world posterior inference in misspecified SBI by translating labeled simulator observations toward the real-world domain and back while using original labels to preserve parameter-relevant mutual information, with gains becoming clearer as misspecification increases.

C2weakest assumption

The assumption that the learned real-to-simulator transport map preserves the mutual information between observations and parameters sufficiently well that the downstream SBI posterior remains accurate, even though no real-world parameter labels are available during training or testing.

C3one line summary

SPIN performs bidirectional domain transfer in SBI to retain parameter mutual information from unlabeled real observations, improving real-world posterior inference under increasing misspecification.
