An Empirical Comparison of Flat and Hierarchical Performance Measures for Multi-Label Classification with Hierarchy Extraction [chapter]

Florian Brucker, Fernando Benites, Elena Sapozhnikova
2011 Lecture Notes in Computer Science  
In contrast to Hierarchical Multi-label Classification (HMC), where the class hierarchy is assumed to be known a priori, we are interested in the opposite case where it is unknown and should be extracted  ...  In this case the predictive performance of a classifier can be assessed by well-known Performance Measures (PMs) used in flat MC such as precision and recall.  ...  In this setting, the predictive performance of a multi-label classifier can be assessed either by well-known Performance Measures (PMs) used in flat multi-label classification such as precision and recall  ...

Inducing a hierarchy for multi-class classification problems [article]

Hayden S. Helm, Weiwei Yang, Sujeeth Bharadwaj, Kate Lytvynets, Oriana Riva, Christopher White, Ali Geisa, Carey E. Priebe
2021 arXiv   pre-print
In this paper, we investigate a class of methods that induce a hierarchy that can similarly improve classification performance over flat classifiers.  ...  The class of methods follows the structure of first clustering the conditional distributions and subsequently using a hierarchical classifier with the induced hierarchy.  ...  In particular, when a latent hierarchy exists this structure can be inferred and used for hierarchical classification to improve performance in particular parameter settings.  ...

On exploiting hierarchical label structure with pairwise classifiers

Johannes Fürnkranz, Jan Frederik Sima
2011 SIGKDD Explorations  
The goal of this work was to test whether the performance of a regular pairwise classifier can be improved when additional information about the hierarchical class structure is added to the training sets  ...  We explain this with the fact that the structure of the class hierarchy is not reflected in the distribution of the instances.  ...  Acknowledgments: This research was supported by the German Science Foundation (DFG). We would like to thank Eyke Hüllermeier for inspiring discussions on this subject.  ...

Hierarchical Class-Based Curriculum Loss [article]
