jsonnet

We use the same crawler from Quirk et al. to crawl recipes from IFTTT.com.

Processed data can be found in here.

We additional provide a preprocessed dataset derived from Zapier recipes crawled using a crawler.

Processed data can be found under this folder.

The code includes the implementation of following models:

• BDLSTM+LA: in configs/model.jsonnet, set model/name to be "rnn", model/decoder to be "LA".
• BDLSTM+A: in configs/model.jsonnet, set model/name to be "rnn", model/decoder to be "attention".
• BDLSTM: in configs/model.jsonnet, set model/name to be "rnn", don't set model/decoder(delete this line or set it to "").
• Dict+LA: in configs/model.jsonnet, set model/name to be "Dict", model/decoder to be "LA".
• Dict+A: in configs/model.jsonnet, set model/name to be "Dict", model/decoder to be "attention".
• Dict: in configs/model.jsonnet, set model/name to be "Dict", don't set model/decoder(delete this line or set it to "").

In the following we list some important arguments in train.py:

• --dataset: path to the preprocessed dataset.
• --load-model: path to the pretrained model (optional).
• --config: path to the file that stores the configuration of model architecture.
• --logdir: path to the directory that stores the models (optional).
• --output: name of the file that stores the prediction results (no need to specify the filename extension, the output is a pickle (.pkl) file).

python train.py --dataset dataset/IFTTT/msr_data.pkl --config configs/model.jsonnet --logdir model --output result

To ensemble results of several models:

python test_ensemble_probs.py --data dataset/IFTTT/msr_data.pkl --res result_0.pkl result_1.pkl ... result_N.pkl
