Is margin preserved after random projection?
Qinfeng Shi, Chunhua Shen, Rhys Hill +1
Random projections have been applied in many machine learning algorithms. However, whether margin is preserved after random projection is non-trivial and not well studied. In this…

Non-sparse Linear Representations for Visual Tracking with Online Reservoir Metric Learning
Xi Li, Chunhua Shen, Qinfeng Shi +2
Most sparse linear representation-based trackers need to solve a computationally expensive L1-regularized optimization problem. To address this problem, we propose a visual tracker…

Conditional Random Fields and Support Vector Machines: A Hybrid Approach
Qinfeng Shi, Mark D. Reid, Tiberio Caetano
We propose a novel hybrid loss for multiclass and structured prediction problems that is a convex combination of log loss for Conditional Random Fields (CRFs) and a multiclass hing…
