Hi-Transformer: Hierarchical Interactive Transformer for Efficient and Effective Long Document Modeling [article]

Chuhan Wu, Fangzhao Wu, Tao Qi, Yongfeng Huang
2021 arXiv   pre-print
In order to handle this problem, we propose a hierarchical interactive Transformer (Hi-Transformer) for efficient and effective long document modeling.  ...  Extensive experiments on three benchmark datasets validate the efficiency and effectiveness of Hi-Transformer in long document modeling.  ...  We are grateful to Xing Xie, Shaoyu Zhou, Dan Shen, and Zhisong Wang for their insightful comments and suggestions on this work.  ...

A Survey of Transformers [article]

Tianyang Lin, Yuxin Wang, Xiangyang Liu, Xipeng Qiu
2021 arXiv   pre-print
We first briefly introduce the vanilla Transformer and then propose a new taxonomy of X-formers.  ...  Next, we introduce the various X-formers from three perspectives: architectural modification, pre-training, and applications. Finally, we outline some potential directions for future research.  ...  Hi-Transformer [145] first utilizes a sentence Transformer and a document Transformer to hierarchically learn document context-aware sentence representations.  ...

Re-Thinking the Value of Learning Theories to Develop Self-Directedness in Open-Distance Students

Bernadette Geduld
2014 Journal of Educational and Social Research  
The concern is raised whether there is a single "best" learning theory and whether one theory is more efficient than the others when it comes to adult learners in ODL.  ...  Learning is a complex process that has generated numerous interpretations and theories as to how exactly it can be effectively facilitated to ensure that meaningful learning is achieved.  ...  The evolution of learning theories and their use for effective teaching and learning have been researched and documented (Pritchard, 2009; Conlan et al., 2008) .  ...
