|
|
|
|
This is a TensorFlow implementation of Diffusion Convolutional Recurrent Neural Network in the following paper: \

|
|
|
## Requirements
|
|
- hyperopt>=0.1
|
|
- scipy>=0.19.0
|
|
- numpy>=1.12.1
|
|
- pandas>=0.19.2
|
|
- tensorflow>=1.3.0
|
|
- pyaml
|
|
|
|
|
|
Dependency can be installed using the following command:
|
|
```bash
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
|
|
## Traffic Data
|
|
The traffic data file for Los Angeles, i.e., df_highway_2012_4mon_sample.h5, is available [here](https://drive.google.com/open?id=1tjf5aXCgUoimvADyxKqb-YUlxP8O46pb), and should be
|
|
put into the `data/` folder.
|
|
Besides, the locations of sensors are available at [data/sensor_graph/graph_sensor_locations.csv](https://github.com/liyaguang/DCRNN/blob/master/data/sensor_graph/graph_sensor_locations.csv).
|
|
|
|
## Graph Construction
|
|
As the currently implementation is based on pre-calculated road network distances between sensors, it currently only
|
|
supports sensor ids in Los Angeles (see `data/sensor_graph/sensor_info_201206.csv`).
|
|
|
|
```bash
|
|
python gen_adj_mx.py --sensor_ids_filename=data/sensor_graph/graph_sensor_ids.txt --normalized_k=0.1\
|
|
--output_pkl_filename=data/sensor_graph/adj_mx.pkl
|
|
```
|
|
|
|
## Train the Model
|
|
```bash
|
|
python dcrnn_train.py --config_filename=data/model/dcrnn_config.yaml
|
|
```
|
|
|
|
|
|
## Run the Pre-trained Model
|
|
|
|
```bash
|
|
python run_demo.py
|
|
```
|
|
The generated prediction of DCRNN is in `data/results/dcrnn_predictions_[1-12].h5`.
