Reconstructing the local density field with combined convolutional and point cloud architecture. Baptiste Barthe-Gold et. al. https://arxiv.org/abs/2510.08573
Schematic representation of our architecture. The backbone is a U-Net evaluated on the velocity divergence. Additional small-scale information is provided by a DeepSets point-cloud architecture which is evaluated locally. Due to the high cost of the DeepSets evaluation, a pretrained and then froz... Performance evaluation in two-point statistics. The left panel shows the cross-correlation coefficient, while the right panel shows the transfer function. Blue is the 3D Wiener filter (which is an upper bound on linear reconstruction), magenta shows the reconstruction with a convolutional U-Net o...
