WebAug 23, 2024 · Another well-known threshold-based ordinal regression method is Support Vector Ordinal Regression (SVOR) [3, 20] that generalize the “large margin” principle adopted by support vector machines to ordinal regression. Two solutions to SVOR have been developed: one maximizes the margin of the closest neighboring classes (called fixed …

WebDec 22, 2024 · Thus far, depression severity is predicted either as a classification or regression task ignoring the ordinality of depression scores. In this paper, we highlight the importance of using ordinal regression algorithms for ordinal response data by comparing with multiclass classification and regression using support vector framework. WebSupport Vector Ordinal Regression. Abstract: In this letter, we propose two new support vector approaches for ordinal regression, which optimize multiple thresholds to define parallel discriminant hyperplanes for the ordinal scales. Both approaches guarantee that the thresholds are properly ordered at the optimal solution. The size of these ...
