Models

2-Parameter Model (`2param/`)

DDPM model with 2 parameters for HI map generation.

Original repository: collins909/DDPM-2param

6-Parameter Model (`6param/`)

DDPM model with 6 labels/parameters for HI map generation.

Original repository: collins909/DDPM-6param

Research Context

These models are part of research on emulating large-scale neutral hydrogen (HI) maps using score-based diffusion models trained on CAMELS simulation data.

Usage

Each model variant is contained in its respective folder with all necessary files.

# Example: Load the 6-parameter model
from diffusers import DDPMPipeline

pipeline = DDPMPipeline.from_pretrained("collins909/DDPM-HI-models/6param")
