Memory Group Sampling Based Online Action Recognition Using Kinetic Skeleton Features

no code implementations1 Nov 2020 Guoliang Liu, Qinghui Zhang, Yichao Cao, Junwei Li, Hao Wu, Guohui Tian

First, we combine the spatial and temporal skeleton features to depict the actions, which include not only the geometrical features, but also multi-scale motion features, such that both the spatial and temporal information of the action are covered.

DiffNet++: A Neural Influence and Interest Diffusion Network for Social Recommendation

2 code implementations15 Jan 2020 Le Wu, Junwei Li, Peijie Sun, Richang Hong, Yong Ge, Meng Wang

Recently, we propose a preliminary work of a neural influence diffusion network (i. e., DiffNet) for social recommendation (Diffnet), which models the recursive social diffusion process to capture the higher-order relationships for each user.
