Support Vector Ordinal Regression [PDF]

Neural Computation, 2007
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.

Exploiting Structured Global and Neighbor Orders for Enhanced Ordinal Regression

Information
Ordinal regression combines classification and regression techniques, constrained by the intrinsic order among categories. It has wide-ranging applications in real-world scenarios, such as product quality grading, medical diagnoses, and facial age ...

Active Learning for Imbalanced Ordinal Regression

IEEE Access, 2020
Ordinal regression (OR), also called ordinal classification, is a special multi-classification designed for problems with ordered classes. Imbalanced data hinders the performance of classification algorithms, especially for OR algorithms, as imbalanced ...

Convolutional Ordinal Regression Forest for Image Ordinal Estimation [PDF]

IEEE Transactions on Neural Networks and Learning Systems, 2022
Image ordinal estimation is to predict the ordinal label of a given image, which can be categorized as an ordinal regression problem. Recent methods formulate an ordinal regression problem as a series of binary classification problems. Such methods cannot ensure that the global ordinal relationship is preserved since the relationships among different ...

Smoothing in Ordinal Regression: An Application to Sensory Data

Stats, 2021
The so-called proportional odds assumption is popular in cumulative, ordinal regression. In practice, however, such an assumption is sometimes too restrictive.

Ordinal Ridge Regression with Categorical Predictors [PDF]

, 2011
In multi-category response models categories are often ordered. In case of ordinal response models, the usual likelihood approach becomes unstable with ill-conditioned predictor space or when the number of parameters to be estimated is large relative to ...
