WebApr 1, 2024 · In this paper, we address the multi-view OR problem with data uncertainty, and put forward a novel model, called multi-view support vector ordinal regression with data uncertainty (MORU). MORU introduces a bound to the uncertain data. Then, the uncertain information is incorporated into a multi-view OR model. WebJan 1, 2024 · Support vector ordinal regression (SVOR) is an appealing method to tackle ordinal regression problems. However, due to the complexity in the formulation of SVOR and the high cost of kernel computation, traditional SVOR solvers are inefficient for large-scale training. To address this problem, in this paper, we first highlight a special SVOR ...
