Adding A Filter Based on The Discriminator to Improve Unconditional Text Generation

1 code implementation5 Apr 2020 Xingyuan Chen, Ping Cai, Peng Jin, Hongjun Wang, Xin-yu Dai, Jia-Jun Chen

R3: A Reading Comprehension Benchmark Requiring Reasoning Processes

no code implementations2 Apr 2020 Ran Wang, Kun Tao, Dingjie Song, Zhilong Zhang, Xiao Ma, Xi'ao Su, Xin-yu Dai

Existing question answering systems can only predict answers without explicit reasoning processes, which hinder their explainability and make us overestimate their ability of understanding and reasoning over natural language.

A Reinforced Generation of Adversarial Examples for Neural Machine Translation

1 code implementation ACL 2020 Wei Zou, Shu-Jian Huang, Jun Xie, Xin-yu Dai, Jia-Jun Chen

Neural machine translation systems tend to fail on less decent inputs despite its significant efficacy, which may significantly harm the credibility of this systems-fathoming how and when neural-based systems fail in such cases is critical for industrial maintenance.

Fine-grained Knowledge Fusion for Sequence Labeling Domain Adaptation

no code implementations IJCNLP 2019 Huiyun Yang, Shu-Jian Huang, Xin-yu Dai, Jia-Jun Chen

In sequence labeling, previous domain adaptation methods focus on the adaptation from the source domain to the entire target domain without considering the diversity of individual target domain samples, which may lead to negative transfer results for certain samples.

Neural Machine Translation with Word Predictions

no code implementations EMNLP 2017 Rongxiang Weng, Shu-Jian Huang, Zaixiang Zheng, Xin-yu Dai, Jia-Jun Chen

In the encoder-decoder architecture for neural machine translation (NMT), the hidden states of the recurrent structures in the encoder and decoder carry the crucial information about the sentence. These vectors are generated by parameters which are updated by back-propagation of translation errors through time.
