ACL changes the policy of Arxiv submission

According to the new ACL submission policy for submitting papers to preprint services such as Arxiv, there is a period that all ACL submissions are forbidden to be submitted to Arxiv. The period begins one month before the submission deadline and ends at the notification date. The changing does a lot of impact for NLP researchers. Some people just get used to posting their paper on Arxiv right after the submission; this is strictly forbidden now. If you want to submit to Arxiv, then do it one month before the deadline.
As the length of the period is about two months, which means that in this two months, NLP researchers can reduce the frequency of checking Arxiv papers, just like a holiday. However, it will also have a negative impact. For researchers also want to submit to ICLR,  they have to carefully check the schedule of ACL submissions. It is possible that the forbidding period conflicts with the submission deadline of ICLR, then the researchers have to choose to submit to either conference.

ACL 2017 first day review

Machine Translation Session

A Convolutional Encoder Model for Neural Machine Translation

Jonas Gehring, Michael Auli, David Grangier and Yann Dauphin

  • The encoder is replaced by convolutional networks
  • Position embeddings are used
  • Two-stack architecture: there are two separate nets predicting the key and value for the attention
  • Interestingly, the author does not use two-stack architecture in their later research

Deep Neural Machine Translation with Linear Associative

Mingxuan Wang, Zhengdong Lu, Jie Zhou and Qun Liu

  • The residual connection is introduced inside the gate function, modified from GRU
  • It’s quite interesting the gain is very large by just replacing GRU with LAU

Alternative Objective Functions for Training MT Evaluation

Miloš Stanojević and Khalil Sima’an

  • A training-based evaluation method for machine translation
  • The evaluate itself is done by looking at the kendall’s tau agianst the human ranking data

General review of the conference

The accecpted papers tend to have a detailed comparison with other related methods, rather than just interesting. Beside the experiments, the structure of paper is usually clear and supports the core idea. This point is also reflected by classifying the sentiment (figure below). In the poster session, I have found the papers very diverse, there are quite a lot papers solving problems that I didn’t heard about.

Many people have different backgrounds, and some of them are not in the academia.People I have talked include entrepreneurs, recruiters and general managers. The nice thing about the hotel is the free coffee and food. Awesome experience.
