Investigating Transfer Learning in Multilingual Pre-trained Language Models through Chinese Natural Language Inference

1 code implementation Findings (ACL) 2021 Hai Hu, He Zhou, Zuoyu Tian, Yiwen Zhang, Yina Ma, Yanting Li, Yixin Nie, Kyle Richardson

These results, however, come with important caveats: cross-lingual models often perform best when trained on a mixture of English and high-quality monolingual NLI data (OCNLI), and are often hindered by automatically translated resources (XNLI-zh).

MUSE: Multi-faceted Attention for Signed Network Embedding

no code implementations29 Apr 2021 Dengcheng Yan, Youwen Zhang, Wei Li, Yiwen Zhang

Signed network embedding is an approach to learn low-dimensional representations of nodes in signed networks with both positive and negative links, which facilitates downstream tasks such as link prediction with general data mining frameworks.

1 code implementation11 Mar 2021 Zhaolong Ling, Kui Yu, Yiwen Zhang, Lin Liu, Jiuyong Li

Causal Learner is a toolbox for learning causal structure and Markov blanket (MB) from data.

Heterogeneous Information Network-based Interest Composition with Graph Neural Network for Recommendation

no code implementations11 Mar 2021 Dengcheng Yan, Wenxin Xie, Yiwen Zhang

Then, users' interests in each item from each pair of related meta-paths are calculated by a combination of the user and item representations.

HyperCI: A Higher Order Collective Influence Measure for Hypernetwork Dismantling

no code implementations10 Mar 2021 Dengcheng Yan, Zijian Wu, Yiwen Zhang

However, conventional network dismantling approaches focus on simple network which models only pairwise interaction between nodes while groupwise interactions among arbitrary number of nodes are ubiquitous in networked systems like integrated circuits.

Path of Vowel Raising in Chengdu Dialect of Mandarin

no code implementations11 Mar 2018 Hai Hu, Yiwen Zhang

He and Rao (2013) reported a raising phenomenon of /a/ in /Xan/ (X being a consonant or a vowel) in Chengdu dialect of Mandarin, i. e. /a/ is realized as [epsilon] for young speakers but [ae] for older speakers, but they offered no acoustic analysis.
