Unsupervised bilingual lexicon induction naturally exhibits duality, which results from symmetry in back-translation. For example, EN-IT and IT-EN induction can be mutually primal and dual problems. ...
In this paper, we propose to train primal and dual models jointly, using regularizers to encourage consistency in back translation cycles. ...
