Robust Elastic Net Regression
Weiyang Liu, Rongmei Lin, Meng Yang
We propose a robust elastic net (REN) model for high-dimensional sparse regression and give its performance guarantees (both the statistical error bound and the optimization bound)…
Jointly Learning Non-negative Projection and Dictionary with Discriminative Graph Constraints for Classification
Weiyang Liu, Zhiding Yu, Yandong Wen +2
Sparse coding with dictionary learning (DL) has shown excellent classification performance. Despite the considerable number of existing works, how to obtain features on top of whic…
Efficient Face Alignment via Locality-constrained Representation for Robust Recognition
Yandong Wen, Weiyang Liu, Meng Yang +1
Practical face recognition has been studied in the past decades, but still remains an open challenge. Current prevailing approaches have already achieved substantial breakthroughs…
Structured Occlusion Coding for Robust Face Recognition
Yandong Wen, Weiyang Liu, Meng Yang +3
Occlusion in face recognition is a common yet challenging problem. While sparse representation based classification (SRC) has been shown promising performance in laboratory conditi…
