#Stochastic Weight Completion

This is a TensorFlow implementation of Stochastic Weight Completion for Road Networks, as described in our paper:

Jilin Hu, Chenjuan Guo, Bin Yang, Christian S. Jensen, Stochastic Weight Completion for Road Networks Using Graph Convolutional Networks (ICDE 2019)

Requirements

• tensorflow (>0.12)

Run the demo

python gcrn_main_gcnn.py

Data

In order to use your own data, you have to provide

• an N by N adjacency matrix (N is the number of nodes),
• an N by D feature matrix (D is the number of features per node), and

Have a look at the BatchLoader class in utils.py for an example.

You can specify a dataset as follows:

python gcrn_main_gcnn.py --server_name='chengdu'

(or by editing gcrn_main_gcnn.py)
