An Unsupervised Multiple-Task and Multiple-Teacher Model for Cross-lingual Named Entity Recognition

no code implementations ACL 2022 Zhuoran Li, Chunming Hu, Xiaohui Guo, Junfan Chen, Wenyi Qin, Richong Zhang

In this study, based on the knowledge distillation framework and multi-task learning, we introduce the similarity metric model as an auxiliary task to improve the cross-lingual NER performance on the target domain.

Robust Regularization with Adversarial Labelling of Perturbed Samples

no code implementations28 May 2021 Xiaohui Guo, Richong Zhang, Yaowei Zheng, Yongyi Mao

The ALPS regularization objective is formulated as a min-max problem, in which the outer problem is minimizing an upper-bound of the VRM loss, and the inner problem is L$_1$-ball constrained adversarial labelling on perturbed sample.
