  • found dropout bug, fix it, and reran baseline: baseline 35.21, baseline(outproj=emb) 35.24
  • tried several embed set models, failed
  • embedded other words to model embedding space (trained on train data not big data), and then directly used in baseline(outproj=emb)
30000 50000 70000 90000
35.24 34.52 33.73 33.16
4564 (6666) 4535 4469 4426
  • m-nmt is running
  • get word2vec on big data, and compare with word2vec from train data
  • test m-nmt model, increase vocab size and test
  • review zh-uy/uy-zh related works, start to write paper
