Pishgu: Universal Path Prediction Network Architecture for Real-time Cyber-physical Edge Systems

This repo contains the official Pytorch implementation of paper "Pishgu: : Universal Path Prediction Network Architecture for Real-time Cyber-physical Edge Systems" accepted to be published and presented at IEEE/ACM ICCPS 2023. We present a universal architecture for trajectory prediction for pedestrians and vehicles from various points of view specifically designed for CPS applications. Pishgu is lightweight and captures the interdependencies between subjects using Graph Isomorphism Network (GIN). Morevover, by utilizing attentive convolutional layers, Pishgu is able to focus on more informative features and define a novel approach for trajectory prediction.

Domains and Datasets

• Vehicle Bird's-eye View: NGSIM Dataset
• Pedestrian Bird's-eye View: UCY and ETH Datasets
• Pedestrian High-angle View: VIRAT/ActEV Dataset

You can download the preprocessed data from this link.

Installation

git clone https://github.com/TeCSAR-UNCC/Pishgu.git
cd Pishgu
pip install -r requirments.txt

Training and Testing

Each domain has a corresponding Config file in configs folder. For training and saving the model in the Training section just set the "save_model" and "train" fields to True and use the following command:

python3 main.py --config {path_to_the_config_file}

For testing, just give the path to desired model in the config file and set "save_model" and "train" fields to False and use the same command:

python3 main.py --config {path_to_the_config_file}

We also provide the trained weights in all domains in the the "model" folder.
