A Simple Homotopy Proximal Mapping for Compressive Sensing
Tianbao Yang, Lijun Zhang, Rong Jin +2
In this paper, we present a novel yet simple homotopy proximal mapping algorithm for compressive sensing. The algorithm adopts a simple proximal mapping of the norm at eac…
On Data Preconditioning for Regularized Loss Minimization
Tianbao Yang, Rong Jin, Shenghuo Zhu +1
In this work, we study data preconditioning, a well-known and long-existing technique, for boosting the convergence of first-order methods for regularized loss minimization. It is…
CUR Algorithm with Incomplete Matrix Observation
Rong Jin, Shenghuo Zhu
CUR matrix decomposition is a randomized algorithm that can efficiently compute the low rank approximation for a given rectangle matrix. One limitation with the existing CUR algori…
Fine-Grained Visual Categorization via Multi-stage Metric Learning
Qi Qian, Rong Jin, Shenghuo Zhu +1
Fine-grained visual categorization (FGVC) is to categorize objects into subordinate classes instead of basic classes. One major challenge in FGVC is the co-occurrence of two issues…
