1. To reproduce results in normal biased tests:

   cd ./code
   python reduction.py --dataset ml-1m --model nfm --alpha 0
   # dataset: {'ml-1m','book','kuairand'}
   # model: {'fm', 'nfm'}
   # alpha: 1->basemodel; 0->reduction

2. To reproduce results in debiased tests:

   cd ./code
   # model: {'fm', 'nfm'}
   # reconstruction: 0->basemodel; 1->reconstruction
   python reconstruction.py --reconstruction 1 --model nfm
