ActSTD

The official implementation of: Activity Trajectory Generation via Modeling Spatiotemporal Dynamics (KDD '22).

Installation

Environment

Tested OS: Linux
Python >= 3.7
PyTorch == 1.7.1

Dependencies

Install PyTorch 1.7.1 with the correct CUDA version.
Use the pip install -r requirements. txt command to install all of the Python modules and packages used in this project.

run python src/setup.py build_ext --inplace to create the shared object file in the current directory.

Model Training

cd src

Use the following command to train ActSTD on Mobile dataset with different CNF models:

python app.py --data Mobile --model attncnf --tpp neural --l2_attn --ode_method 'scipy_solver' --ode_solver 'RK45' --cuda_id 0 --tpp_style 'gru' --weekhour

python app.py --data Mobile --model jumpcnf --tpp neural --solve_reverse --ode_method 'scipy_solver' --ode_solver 'RK45' --cuda_id 0 --tpp_style 'gru' --weekhour

Use the following command to train ActSTD on Foursquare dataset with different CNF models:

python app.py --data Foursquare --model attncnf --tpp neural --l2_attn --ode_method 'scipy_solver' --ode_solver 'RK45' --cuda_id 0 --tpp_style 'gru' --weekhour

python app.py --data Foursquare --model jumpcnf --tpp neural --solve_reverse --ode_method 'scipy_solver' --ode_solver 'RK45' --cuda_id 0 --tpp_style 'gru' --weekhour
