Cosmological Field Emulation and Parameter Inference with Diffusion Models

no code implementations12 Dec 2023 Nayantara Mudur, Carolina Cuesta-Lazaro, Douglas P. Finkbeiner

Cosmological simulations play a crucial role in elucidating the effect of physical parameters on the statistics of fields and on constraining parameters given information on density fields.

A point cloud approach to generative modeling for galaxy surveys at the field level

1 code implementation28 Nov 2023 Carolina Cuesta-Lazaro, Siddharth Mishra-Sharma

We introduce a diffusion-based generative model to describe the distribution of galaxies in our Universe directly as a collection of points in 3-D space (coordinates) optionally with associated attributes (e. g., velocities and masses), without resorting to binning or voxelization.

Probabilistic reconstruction of Dark Matter fields from biased tracers using diffusion models

1 code implementation14 Nov 2023 Core Francisco Park, Victoria Ono, Nayantara Mudur, Yueying Ni, Carolina Cuesta-Lazaro

Galaxies are biased tracers of the underlying cosmic web, which is dominated by dark matter components that cannot be directly observed.

XNet: A convolutional neural network (CNN) implementation for medical X-Ray image segmentation suitable for small datasets

2 code implementations3 Dec 2018 Joseph Bullock, Carolina Cuesta-Lazaro, Arnau Quera-Bofarull

X-Ray image enhancement, along with many other medical image processing applications, requires the segmentation of images into bone, soft tissue, and open beam regions.
