Local overlap reduction procedure for dynamic ensemble selection

1 code implementation16 Jun 2022 Mariana A. Souza, Robert Sabourin, George D. C. Cavalcanti, Rafael M. O. Cruz

Class imbalance is a characteristic known for making learning more challenging for classification models as they may end up biased towards the majority class.

Multi-label learning for dynamic model type recommendation

1 code implementation1 Apr 2020 Mariana A. Souza, Robert Sabourin, George D. C. Cavalcanti, Rafael M. O. Cruz

Our proposed framework builds a multi-label meta-classifier responsible for recommending a set of relevant model types based on the local data complexity of the region surrounding each test sample.

Online local pool generation for dynamic classifier selection: an extended version

no code implementations5 Sep 2018 Mariana A. Souza, George D. C. Cavalcanti, Rafael M. O. Cruz, Robert Sabourin

Thus, we propose in this work an online pool generation method that produces a locally accurate pool for test samples in difficult regions of the feature space.
