Testing

Run th test.lua to test all the modules in the ggnn and rnn libraries.

Reproducing the bAbI tasks and graph algorithms experiment results

To run the bAbI experiments, and experiments on the two extra sequence tasks:

1. Go into babi/data, run bash get_10_fold_data.sh to get 10 folds of bAbI data for 5 tasks (4, 15, 16, 18, 19) and do some preprocessing.
2. Go into babi/data/extra_seq_tasks, run bash generate_10_fold_data.sh to get 10 folds of data for the two extra sequence tasks.
3. Go back to babi/ and use run_experiments.py to run the GGNN/GGS-NN experiments, e.g. python run_experiments.py babi18 runs GGNN on bAbI task 18 for all 10 folds of data.
4. Use run_rnn_baselines.py to run RNN/LSTM baseline experiments, e.g. python run_rnn_baselines.py babi18 lstm runs LSTM on bAbI task 18 for all 10 folds of data.

Notes

• Make sure "./?.lua" and "./?/init.lua" are on your lua path. For example by export LUA_PATH="./?.lua;./?/init.lua;$LUA_PATH".
• The experiment results may differ slightly from what we reported in the paper, as the datasets are randomly generated and will be different from run to run.
