How To Run The Codes

To train your graph-to-sequence model, you need:

(1) Prepare your train/dev/test data which the form of:

each line is a json object whose keys are "seq", "g_ids", "g_id_features", "g_adj":
"seq" is a text which is supposed to be the output of the decoder
"g_ids" is a mapping from the node ID to its ID in the graph
"g_id_features" is a mapping from the node ID to its text features
"g_adj" is a mapping from the node ID to its adjacent nodes (represented as thier IDs)

See data/no_cycle/train.data as examples.

(2) Modify some hyper-parameters according to your task in the main/configure.py

(3) train the model by running the following code "python run_model.py train -sample_size_per_layer=xxx -sample_layer_size=yyy" The model that performs the best on the dev data will be saved in the dir "saved_model"

(4) test the model by running the following code "python run_model.py test -sample_size_per_layer=xxx -sample_layer_size=yyy" The prediction result will be saved in saved_model/prediction.txt
