Gradient Correction beyond Gradient Descent

no code implementations16 Mar 2022 Zefan Li, Bingbing Ni, Teng Li, Wenjun Zhang, Wen Gao

GCGD consists of two plug-in modules: 1) inspired by the idea of gradient prediction, we propose a \textbf{GC-W} module for weight gradient correction; 2) based on Neural ODE, we propose a \textbf{GC-ODE} module for hidden states gradient correction.

Progressive Stage-wise Learning for Unsupervised Feature Representation Enhancement

no code implementations CVPR 2021 Zefan Li, Chenxi Liu, Alan Yuille, Bingbing Ni, Wenjun Zhang, Wen Gao

For a given unsupervised task, we design multilevel tasks and define different learning stages for the deep network.

Structure Preserving Video Prediction

no code implementations CVPR 2018 Jingwei Xu, Bingbing Ni, Zefan Li, Shuo Cheng, Xiaokang Yang

Despite recent emergence of adversarial based methods for video prediction, existing algorithms often produce unsatisfied results in image regions with rich structural information (i. e., object boundary) and detailed motion (i. e., articulated body movement).
