Official implementation codes of the paper "Regularizing Neural Networks for Future Trajectory Prediction via Inverse Reinforcement Learning Framework"
The paper is submitted to IET Computer Vision and now is under revision. If you want to see the ArXiv version of the paper, visit https://arxiv.org/abs/1907.04525
All the codes were developed on Ubuntu 16.04 with Python 3.5 and Tensorflow 1.10.0. Two folders, Crowd and SDD, in the root directory contains 1) datasets, 2) trained models, and 3) the implementation codes respectively for ETH/UCY and Standford Drone Dataset.
To train the network from scratch, run the followings. The parameters of the trained networks will be stored at the folder saved_1_0.
$ python crowd_train.py --dataset_num 1 --exp_id 0
$ python sdd_train.py --dataset_num 1 --exp_id 0crowd_train.py and sdd_train.py have a number of command-line flags that you can use to configure the model architecture, hyperparameters, and input / output settings. You can find the descriptions in the files.
To test the trained model, run the followings. The program will automatically read the parameters of the train networks in the folder saved_1_0.
$ python crowd_test.py --dataset_num 1 --exp_id 0
