Ensemble of CNN classifiers using Sugeno Fuzzy Integral Technique for Cervical Cytology Image Classification [article]

Rohit Kundu, Hritam Basak, Akhil Koilada, Soham Chattopadhyay, Sukanta Chakraborty, Nibaran Das
2021 arXiv   pre-print
Ensemble Learning is a popular approach for image classification, but simplistic approaches that leverage pre-determined weights to classifiers fail to perform satisfactorily.  ...  The main concern in developing an automatic detection tool for biomedical image classification is the low availability of publicly accessible data.  ...  Hence, we further plan to implement some evolutionary meta-heuristic optimization algorithm for the selection of the fuzzy measures of the classifiers that might further improve the overall classification  ...
