New ADABORD framework improves ordinal classification accuracy

Researchers have introduced ADABORD, a new framework based on AdaBoost specifically designed for ordinal classification tasks. This approach enhances the standard AdaBoost algorithm by incorporating ordinal information into its base estimators and error functions. ADABORD utilizes decision trees with an ordinal Gini splitting criterion and the absolute ranked probability score to account for class ordering and distance. Experiments on the TOC-UCO repository show that ADABORD outperforms seven other state-of-the-art methods, especially on datasets with five or more classes. AI
