Introduction

This repo has implemented a pytorch-based encoder-forecaster model with RNNs including (TrajGRU, ConvLSTM) to do precipitation nowcasting. For more information about TrajGRU, please refer to HKO-7.

If you are interested in my implementation of ConvLSTM and TrajGRU, please see ConvLSTM and TrajGRU. It is assumed that the input shape should be . All of my implementation have been proved to be effective in HKO-7 Dataset. Hopefully it helps your research.

Train

Firstly you should apply for HKO-7 Dataset from HKO-7, and modify somelines in config.py to find the dataset path. Secondly and last, run

python3 experiments/trajGRU_balanced_mse_mae/main.py
, and then run
python3 experiments/trajGRU_frame_weighted_mse/main.py
since I have finetuned the model on the basis of model trained in last step.

Environment

Python 3.6+, PyTorch 1.0 and Ubuntu or macOS.

Demo

Performance

The performance on HKO-7 dataset is below.

CSI HSS Balanced MSE Balanced MAE
