DGDM : Probabilistic Weather Forecasting with Deterministic Guidance-based Diffusion Model

Welcome to the official repository for the Probabilistic Weather Forecasting with Deterministic Guidance-based Diffusion Model. This repository hosts the implementation of DGDM, a novel approach that leverages diffusion model to provide high-accuracy probabilistic weather forecasting.

Getting Started

To make full use of this repository, we recommend following the steps below to set up the environment and download the required datasets.

1. Environment Setup

conda create -n [name] python==3.9
conda activate [name]
pip install -r requirements.txt

2. Datasets

Moving MNIST

The original link was blocked. We replaced it with a different link. If this link doesn't work, download it another way.

cd ./data/moving_mnist
bash download_mmnist.sh

The dataset structure should look like this:

$ tree data/moving_mnist
├── mnist_test_seq.npy
└── train-images-idx3-ubyte.gz

PNW-Typhoon

• Download PWN-Typhoon dataset from Link and place it under data/ directory.

Usage

Once the environment and datasets are prepared, you can begin training and testing the DGDM. Below are instructions for running the model on Moving MNIST; similar steps apply to other datasets.

Train

python main.py -c configs/Template-MovingMNIST.yaml -t -r set/your/save/dir

Test

python main.py -c configs/Template-MovingMNIST.yaml -r set/your/save/dir
