Deep Neural Networks for Rank-Consistent Ordinal Regression Based On Conditional Probabilities

4 code implementations17 Nov 2021 Xintong Shi, Wenzhi Cao, Sebastian Raschka

However, while earlier experiments showed that CORAL's rank consistency is beneficial for performance, it is limited by a weight-sharing constraint in a neural network's fully connected output layer, which may restrict the expressiveness and capacity of a network trained using CORAL.
