Semantically Consistent Data Augmentation for Neural Machine Translation via Conditional Masked Language Model

1 code implementation COLING 2022 Qiao Cheng, Jin Huang, Yitao Duan

In addition, to enhance diversity, we incorporate the idea of soft word substitution for data augmentation which replaces a word with a probabilistic distribution over the vocabulary.

Complex Relation Extraction: Challenges and Opportunities

no code implementations9 Dec 2020 Haiyun Jiang, Qiaoben Bao, Qiao Cheng, Deqing Yang, Li Wang, Yanghua Xiao

In recent years, many complex relation extraction tasks, i. e., the variants of simple binary relation extraction, are proposed to meet the complex applications in practice.

Collective Loss Function for Positive and Unlabeled Learning

no code implementations6 May 2020 Chenhao Xie, Qiao Cheng, Jiaqing Liang, Lihan Chen, Yanghua Xiao

On the contrary, traditional machine learning algorithms often rely on negative examples, otherwise the model would be prone to collapse and always-true predictions.

Breaking the Data Barrier: Towards Robust Speech Translation via Adversarial Stability Training

no code implementations EMNLP (IWSLT) 2019 Qiao Cheng, Meiyuan Fang, Yaqian Han, Jin Huang, Yitao Duan

A standard machine translation system is usually trained on parallel corpus composed of clean text and will perform poorly on text with recognition noise, a gap well known in speech translation community.
