Non-linear Learning for Statistical Machine Translation

no code implementations IJCNLP 2015 Shujian Huang, Huadong Chen, Xin-yu Dai, Jia-Jun Chen

The linear combination assumes that all the features are in a linear relationship and constrains that each feature interacts with the rest features in an linear manner, which might limit the expressive power of the model and lead to a under-fit model on the current data.

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.

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.
