Learning Dynamic Tetrahedra for High-Quality Talking Head Synthesis

1 code implementation27 Feb 2024 ZiCheng Zhang, Ruobing Zheng, Ziwen Liu, Congying Han, Tianqi Li, Meng Wang, Tiande Guo, Jingdong Chen, Bonan Li, Ming Yang

Recent works in implicit representations, such as Neural Radiance Fields (NeRF), have advanced the generation of realistic and animatable head avatars from video sequences.

Masked Reconstruction Contrastive Learning with Information Bottleneck Principle

no code implementations15 Nov 2022 Ziwen Liu, Bonan Li, Congying Han, Tiande Guo, Xuecheng Nie

In order to alleviate the discriminative information overfitting problem effectively, we employ the reconstruction task to regularize the discriminative task.

Learning Graph Representation by Aggregating Subgraphs via Mutual Information Maximization

no code implementations24 Mar 2021 Chenguang Wang, Ziwen Liu

For this purpose, we propose a universal framework to generate subgraphs in an auto-regressive way and then using these subgraphs to guide the learning of graph representation by Graph Neural Networks.

Blocked and Hierarchical Disentangled Representation From Information Theory Perspective

no code implementations21 Jan 2021 Ziwen Liu, Mingqiang Li, Congying Han

It is well known that information theory has an excellent explanatory meaning for the network, so we start to solve the disentanglement problem from the perspective of information theory.
