Target Foresight Based Attention for Neural Machine Translation

no code implementations NAACL 2018 Xintong Li, Lemao Liu, Zhaopeng Tu, Shuming Shi, Max Meng

In neural machine translation, an attention model is used to identify the aligned source words for a target word (target foresight word) in order to select translation context, but it does not make use of any information of this target foresight word at all.

Generative Stock Question Answering

no code implementations21 Apr 2018 Zhaopeng Tu, Yong Jiang, Xiaojiang Liu, Lei Shu, Shuming Shi

We study the problem of stock related question answering (StockQA): automatically generating answers to stock related questions, just like professional stock analysts providing action recommendations to stocks upon user's requests.
