Our experiment are based on POG dataset. We reprocess the data and save the files, and the file format is listed in Data/pog.

python model.py -regs 1e-5 --embed_size 64 --batch_size 1024

For Fill in the Blank (FLTB) task, we only optimize the compatibility loss: L_{com}.

For Personalized outfit Recommendation task, we use the pretrained FLTB model to intialized the whole model to obtain better performance.
