Low Rank Approximation of Binary Matrices: Column Subset Selection and Generalizations
Chen Dan, Kristoffer Arnsfelt Hansen, He Jiang +2
Low rank matrix approximation is an important tool in machine learning. Given a data matrix, low rank approximation helps to find factors, patterns and provides concise representat…
On the Depth of Deep Neural Networks: A Theoretical View
Shizhao Sun, Wei Chen, Liwei Wang +2
People believe that depth plays an important role in success of deep neural networks (DNN). However, this belief lacks solid theoretical justifications as far as we know. We invest…
Image classification by visual bag-of-words refinement and reduction
Zhiwu Lu, Liwei Wang, Ji-Rong Wen
This paper presents a new framework for visual bag-of-words (BOW) refinement and reduction to overcome the drawbacks associated with the visual BOW model which has been widely used…
Pairwise Constraint Propagation on Multi-View Data
Zhiwu Lu, Liwei Wang
This paper presents a graph-based learning approach to pairwise constraint propagation on multi-view data. Although pairwise constraint propagation has been studied extensively, pa…
