Truncated Cauchy Non-negative Matrix Factorization
Naiyang Guan, Tongliang Liu, Yangmuzi Zhang +2
Non-negative matrix factorization (NMF) minimizes the Euclidean distance between the data matrix and its low rank approximation, and it fails when applied to corrupted data because…
Generating Discriminative Object Proposals via Submodular Ranking
Yangmuzi Zhang, Zhuolin Jiang, Xi Chen +1
A multi-scale greedy-based object proposal generation approach is presented. Based on the multi-scale nature of objects in images, our approach is built on top of a hierarchical se…
Parameterizing Region Covariance: An Efficient Way To Apply Sparse Codes On Second Order Statistics
Xiyang Dai, Sameh Khamis, Yangmuzi Zhang +1
Sparse representations have been successfully applied to signal processing, computer vision and machine learning. Currently there is a trend to learn sparse models directly on stru…
Layer-Specific Adaptive Learning Rates for Deep Networks
Bharat Singh, Soham De, Yangmuzi Zhang +2
The increasing complexity of deep learning architectures is resulting in training time requiring weeks or even months. This slow training is due in part to vanishing gradients, in…
What makes an Image Iconic? A Fine-Grained Case Study
Yangmuzi Zhang, Diane Larlus, Florent Perronnin
A natural approach to teaching a visual concept, e.g. a bird species, is to show relevant images. However, not all relevant images represent a concept equally well. In other words,…
