To train a new model (default settings are recorded in the run.py)

python run.py --data=foursquare --model=ERPC --pretrain=1 --pretrain_unit=ERCF

E: embedding, R: rnn, P: pooling, C: co-attention, F: fully connected network. ERPC is the default model in paper, model name can also be ERC(without pooling). ERCF is the default pretrain mode in paper, which means all the components in the model are pretrained. You can choose E, R, C, F for only pretrain selected component and N is for non-pretrain.

Baselines from traditional baselines, TULER and t2vec. Some codes from OpenNMT-py, InferSent and awd-lstm-lm.
