Eradicating Negative Transfer in Multi-Physics Foundation Models via Sparse Mixture-of-Experts Routing

Arastu Sharma, Ellwil Sharma

Shodh-MoE uses Top-1 routing on compressed latents from a divergence-free autoencoder to let distinct physics regimes train separate experts, yielding low MSE and autonomous domain separation in mixed pretraining.

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

These results support sparse expert routing as a practical architectural mechanism for mitigating multi-physics interference in universal neural operators.

C2weakest assumption

That a Top-1 soft-semantic router will reliably produce autonomous domain bifurcation and specialized parameter paths for incompatible PDE regimes without losing shared symmetries or requiring extensive hyperparameter tuning.
