A New Adjacency Matrix Configuration in GCN-based Models for Skeleton-based Action Recognition

no code implementations29 Jun 2022 Zheng Fang, Xiongwei Zhang, Tieyong Cao, Yunfei Zheng, Meng Sun

Comprehensive experimental results and analysis reveals that 1) the most widely used human natural skeleton structure adjacency matrix is unsuitable in skeleton-based action recognition; 2) The proposed adjacency matrix is superior in model performance, noise robustness and transferability.

Knowledge Distillation based Ensemble Learning for Neural Machine Translation

no code implementations1 Jan 2021 Chenze Shao, Meng Sun, Yang Feng, Zhongjun He, Hua Wu, Haifeng Wang

Under this framework, we introduce word-level ensemble learning and sequence-level ensemble learning for neural machine translation, where sequence-level ensemble learning is capable of aggregating translation models with different decoding strategies.
