Task: Language Identification
Input (Spanish, English):  It has recently come to my attention that the objective proposed by the authors in this paper has in fact already been studied in the literature under the name 'reward-weighted regression', from e.g. ICML 2007 [1]. This has spawned several other works using the same objective (e.g. [2]). One can examine for instance the objective proposed in Section 3.4 from [2], from ICANN 2008.  While this paper has already been accepted to ICLR, it would be beneficial for the authors to at least cite these works (and other related works) so that readers are aware of the previous origins of this idea.
