Gradient-SDF: A Semi-Implicit Surface Representation for 3D Reconstruction
Christiane Sommer, Lu Sang, David Schubert +1
We present Gradient-SDF, a novel representation for 3D geometry that combines the advantages of implict and explicit representations. By storing at every voxel both the signed dist…

Dive into Layers: Neural Network Capacity Bounding using Algebraic Geometry
Ji Yang, Lu Sang, Daniel Cremers
The empirical results suggest that the learnability of a neural network is directly related to its size. To mathematically prove this, we borrow a tool in topological algebra: Bett…
