Zero-shot Skeleton-based Action Recognition via Mutual Information Estimation and Maximization

1 code implementation7 Aug 2023 Yujie Zhou, Wenwen Qiang, Anyi Rao, Ning Lin, Bing Su, Jiaqi Wang

Specifically, 1) we maximize the MI between visual and semantic space for distribution alignment; 2) we leverage the temporal information for estimating the MI by encouraging MI to increase as more frames are observed.

Self-supervised Action Representation Learning from Partial Spatio-Temporal Skeleton Sequences

1 code implementation17 Feb 2023 Yujie Zhou, Haodong Duan, Anyi Rao, Bing Su, Jiaqi Wang

Specifically, we construct a negative-sample-free triplet steam structure that is composed of an anchor stream without any masking, a spatial masking stream with Central Spatial Masking (CSM), and a temporal masking stream with Motion Attention Temporal Masking (MATM).

Chinese Grammatical Error Diagnosis Based on CRF and LSTM-CRF model

no code implementations WS 2018 Yujie Zhou, Yinan Shao, Yong Zhou

When learning Chinese as a foreign language, the learners may have some grammatical errors due to negative migration of their native languages.
