Twin Neural Networks for the Classification of Large Unbalanced Datasets

Jayadeva, Himanshu Pant, Mayank Sharma, Sumit Soman
2019 Neurocomputing  
In this paper, we discuss a Twin Neural Network (Twin NN) architecture for learning from large unbalanced datasets.  ...  The TWSVM learns two non-parallel classifying hyperplanes by solving a couple of smaller sized problems. However, it is unsuitable for large datasets, as it involves matrix operations.  ...  Acknowledgements The corresponding author would like to acknowledge the support of the Microsoft Chair Professor Project Grant (MI01158, IIT Delhi).  ...

Improvements on Twin Support Vector Machines

Yuan-Hai Shao, Chun-Hua Zhang, Xiao-Bo Wang, Nai-Yang Deng
2011 IEEE Transactions on Neural Networks  
Considering the multiple instance learning(MIL) in classification problem, a novel multiple instance twin support vector machines(MI-TWSVM) method is proposed.  ...  For linear classification, unlike other maximum margin SVM-based MIL methods, the proposed approach leads to two non-parallel hyperplanes. The non-linear classification via kernels is also studied.  ...  Improvements on better optimization and evaluation using a wide variety of datasets and algorithms, such as those in [9] , are promising avenues of future research.  ...
