A hybrid approach to learn with imbalanced classes using evolutionary algorithms
(OXFORD UNIV PRESS, 2011)
There is an increasing interest in the application of Evolutionary Algorithms (EAs) to induce classification rules. This hybrid approach can benefit areas where classical methods for rule induction have not been very ...
Metric-Space Approach for Distinguishing Quantum Phase Transitions in Spin-Imbalanced Systems
(Springer, 2018-10-01)
Metric spaces are characterized by distances between pairs of elements. Systems that are physically similar are expected to present smaller distances (between their densities, wave functions, and potentials) than systems ...
Entanglement and exotic superfluidity in spin-imbalanced lattices
(Elsevier B.V., 2017-06-01)
We investigate the properties of entanglement in one-dimensional fermionic lattices at the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superfluid regime. By analyzing occupation probabilities, which are concepts closely related ...
ClusterOSS: a new undersampling method for imbalanced learning
(Universidade de São Paulo - USPUniversidade Federal de São Carlos - UFSCarCentro de Robótica de São Carlos - CROBSociedade Brasileira de Computação - SBCSociedade Brasileira de Automática – SBASão Carlos, 2014-10)
A dataset is said to be imbalanced when its classes are disproportionately represented in terms of the number of instances they contain. This problem is common in applications such as medical diagnosis of rare diseases, ...
Data analysis in python: Anonymized features and imbalanced data target
(2017-04-25)
Remaining useful life (RUL) of an equipment or system is a prognostic value that depends on data gathered from multiple and diverse sources. Moreover, assumed for the sake of the present study as a binary classification ...
Handling imbalanced datasets through Optimum-Path Forest
(2022-04-22)
In the last decade, machine learning-based approaches became capable of performing a wide range of complex tasks sometimes better than humans, demanding a fraction of the time. Such an advance is partially due to the ...
