Neural Machine Translation with Soft Prototype

1 code implementation NeurIPS 2019 Yiren Wang, Yingce Xia, Fei Tian, Fei Gao, Tao Qin, Cheng Xiang Zhai, Tie-Yan Liu

Neural machine translation models usually use the encoder-decoder framework and generate translation from left to right (or right to left) without fully utilizing the target-side global information.

Hint-Based Training for Non-Autoregressive Machine Translation

1 code implementation IJCNLP 2019 Zhuohan Li, Zi Lin, Di He, Fei Tian, Tao Qin, Li-Wei Wang, Tie-Yan Liu

Due to the unparallelizable nature of the autoregressive factorization, AutoRegressive Translation (ART) models have to generate tokens sequentially during decoding and thus suffer from high inference latency.

Depth Growing for Neural Machine Translation

1 code implementation ACL 2019 Lijun Wu, Yiren Wang, Yingce Xia, Fei Tian, Fei Gao, Tao Qin, Jian-Huang Lai, Tie-Yan Liu

While very deep neural networks have shown effectiveness for computer vision and text classification applications, how to increase the network depth of neural machine translation (NMT) models for better translation quality remains a challenging problem.

Hint-based Training for Non-Autoregressive Translation

no code implementations ICLR 2019 Zhuohan Li, Di He, Fei Tian, Tao Qin, Li-Wei Wang, Tie-Yan Liu

To improve the accuracy of NART models, in this paper, we propose to leverage the hints from a well-trained ART model to train the NART model.

Non-Autoregressive Machine Translation with Auxiliary Regularization

no code implementations22 Feb 2019 Yiren Wang, Fei Tian, Di He, Tao Qin, ChengXiang Zhai, Tie-Yan Liu

However, the high efficiency has come at the cost of not capturing the sequential dependency on the target side of translation, which causes NAT to suffer from two kinds of translation errors: 1) repeated translations (due to indistinguishable adjacent decoder hidden states), and 2) incomplete translations (due to incomplete transfer of source side information via the decoder hidden states).

Learning to Teach with Dynamic Loss Functions

no code implementations NeurIPS 2018 Lijun Wu, Fei Tian, Yingce Xia, Yang Fan, Tao Qin, Jian-Huang Lai, Tie-Yan Liu

Different from typical learning settings in which the loss function of a machine learning model is predefined and fixed, in our framework, the loss function of a machine learning model (we call it student) is defined by another machine learning model (we call it teacher).

Beyond Error Propagation in Neural Machine Translation: Characteristics of Language Also Matter

no code implementations EMNLP 2018 Lijun Wu, Xu Tan, Di He, Fei Tian, Tao Qin, Jian-Huang Lai, Tie-Yan Liu

Many previous works have discussed the relationship between error propagation and the \emph{accuracy drop} (i. e., the left part of the translated sentence is often better than its right part in left-to-right decoding models) problem.

Sentence Level Recurrent Topic Model: Letting Topics Speak for Themselves

no code implementations7 Apr 2016 Fei Tian, Bin Gao, Di He, Tie-Yan Liu

We propose Sentence Level Recurrent Topic Model (SLRTM), a new topic model that assumes the generation of each word within a sentence to depend on both the topic of the sentence and the whole history of its preceding words in the sentence.

Solving Verbal Comprehension Questions in IQ Test by Knowledge-Powered Word Embedding

no code implementations29 May 2015 Huazheng Wang, Fei Tian, Bin Gao, Jiang Bian, Tie-Yan Liu

Second, we obtain distributed representations of words and relations by leveraging a novel word embedding method that considers the multi-sense nature of words and the relational knowledge among words (or their senses) contained in dictionaries.

Learning Better Word Embedding by Asymmetric Low-Rank Projection of Knowledge Graph

no code implementations19 May 2015 Fei Tian, Bin Gao, Enhong Chen, Tie-Yan Liu

Although these works have achieved certain success, they have neglected some important facts about knowledge graphs: (i) many relationships in knowledge graphs are \emph{many-to-one}, \emph{one-to-many} or even \emph{many-to-many}, rather than simply \emph{one-to-one}; (ii) most head entities and tail entities in knowledge graphs come from very different semantic spaces.

Generalization Analysis for Game-Theoretic Machine Learning

no code implementations9 Oct 2014 Haifang Li, Fei Tian, Wei Chen, Tao Qin, Tie-Yan Liu

For Internet applications like sponsored search, cautions need to be taken when using machine learning to optimize their mechanisms (e. g., auction) since self-interested agents in these applications may change their behaviors (and thus the data distribution) in response to the mechanisms.

Then we prove a generalization bound for the machine learning algorithms on the behavior data generated by the new Markov chain, which depends on both the Markovian parameters and the covering number of the function class compounded by the loss function for behavior prediction and the behavior prediction model.
