DiffRayve: Differentiable Ray-Wave Method for Polarized and Unpolarized Diffractive-Refractive Optical Systems
Samuel Audia, Shrey Patel, Dinesh Manocha +1
Current deep optics simulations struggle to balance high fidelity with computational efficiency, particularly for complex polarized and diffractive systems. To address this, we int…

How Learnable Grids Recover Fine Detail in Low Dimensions: A Neural Tangent Kernel Analysis of Multigrid Parametric Encodings
Samuel Audia, Soheil Feizi, Matthias Zwicker +1
Neural networks that map between low dimensional spaces are ubiquitous in computer graphics and scientific computing; however, in their naive implementation, they are unable to lea…
