Exact SO(3)-Equivariant Isotropic Kernels for Rotation-Robust Neural Dynamics
Ridham Patel
Neural surrogates for vector-valued partial differential equations can fit training data yet change their predictions when the same physical state is expressed in a rotated coordin…

The Symbol of the Surrogate: Measuring Numerical Provenance in Neural PDE Solvers
Ridham Patel
Neural PDE surrogates are trained on numerical solver outputs that contain both physical evolution and solver-specific discretization errors. Because surrogates are also evaluated…

Measuring Effective Data Resolution in Guided Diffusion Posteriors
Ridham Patel, Defu Cao, Jiacheng Pang +1
Guided diffusion samplers are increasingly used to reconstruct physical fields from sparse observations, but standard diagnostics do not say how much of the reconstruction was actu…
