Both neural networks and decision trees are popular machine learning methods
and are widely used to solve problems from diverse domains. These two
classifiers are commonly used base classifiers in an ensemble framework...
this paper, we first present a new variant of oblique decision tree based on a
linear classifier, then construct an ensemble classifier based on the fusion of
a fast neural network, random vector functional link network and oblique
decision trees. Random Vector Functional Link Network has an elegant closed
form solution with extremely short training time. The neural network partitions
each training bag (obtained using bagging) at the root level into C subsets
where C is the number of classes in the dataset and subsequently, C oblique
decision trees are trained on such partitions. The proposed method provides a
rich insight into the data by grouping the confusing or hard to classify
samples for each class and thus, provides an opportunity to employ fine-grained
classification rule over the data. The performance of the ensemble classifier
is evaluated on several multi-class datasets where it demonstrates a superior
performance compared to other state-of- the-art classifiers.
