A 4D Gaussian splatting method that adds a Kalman-like state consistency filter and Wasserstein log/exp geometry reports quality gains on dynamic scene benchmarks, but internal equation errors and unverified training-time claims weaken the result.

Gaussians on their Way: Wasserstein-Constrained 4D Gaussian Splatting with State-Space Modeling
A 4D Gaussian splatting method that adds a Kalman-like state consistency filter and Wasserstein log/exp geometry reports quality gains on dynamic scene benchmarks, but internal equation errors and unverified training-time claims weaken the result.
