RANSAC Multi Model Response Regression based Pruned Extreme Learning Machines for Multiclass Problems

The accuracy and performance of machine learning and statistical models are still based on tuning some parameters and optimization for generating better predictive models of learning is based on training data. Larger datasets and
samples are also problematic, due to increase in computational times, complexity and bad generalization due to manually tuning of parameters. Using the motivation from extreme learning machine (ELM), we proposed annular ELM
based on RANSAC Multi Response Regression to prune the large number of hidden nodes to acquire better optimality, generalization and classification accuracy of the network in ELM. Experimental results on different benchmark
datasets showed that proposed algorithm optimally prunes the hidden nodes, better generalization and higher testing accuracy compared to other algorithms, including SVM, OP-ELM for binary and multi-class classification and regression problems.
