SIT

Paper

• This is the official implementation of the paper: Social Interpretable Tree for Pedestrian Trajectory Prediction (AAAI 2022).

Quick Start

Requires:

• Python== 3.6
• numpy==1.16.4
• torch==1.4.0

1) Install Packages

 pip install -r requirements.txt

2) Dataset

Please download the dataset and extract it into the directory './dataset/' like this:

./dataset/train/
./dataset/test/

Performance

Results on ETH-UCY and Stanford Drone Dataset:

	minADE	minFDE
ETH	0.39	0.62
HOTEL	0.14	0.22
UNIV	0.27	0.47
ZARA1	0.19	0.33
ZARA2	0.16	0.29
AVG ETH-UCY	0.23	0.38
SDD	9.13	15.42

Training & Evaluation

Suppose the training data is at ./dataset/. You can train and evaluate our model on the 'eth' dataset by below command:

bash train.sh 'eth'

Training on a single 2080Ti.
