A Pipeline for Optimizing F1-Measure in Multi-label Text Classification
2018
2018 17th IEEE International Conference on Machine Learning and Applications (ICMLA)
Preserved Fulltext
Many classic multi-label learning algorithms focus on incorporating label dependencies in the model training phase and optimize for the strict set-accuracy measure. ...
Multi-label text classification is the machine learning task wherein each document is tagged with multiple labels, and this task is uniquely challenging due to high dimensional features and correlated ...
CONCLUSION In this paper our main goal is to develop a pipeline in order to reuse classic multi-label models to achieve high F1 scores on multi-label text data. ...
