Multi-Objective Optimisation of Multi-Output Neural Trees
Varun Ojha, Giuseppe Nicosia
We propose an algorithm and a new method to tackle the classification problems. We propose a multi-output neural tree (MONT) algorithm, which is an evolutionary learning algorithm…
Predictive modeling of die filling of the pharmaceutical granules using the flexible neural tree
Varun Kumar Ojha, Serena Schiano, Chuan-Yu Wu +2
In this work, a computational intelligence (CI) technique named flexible neural tree (FNT) was developed to predict die filling performance of pharmaceutical granules and to identi…
Convergence Analysis of Backpropagation Algorithm for Designing an Intelligent System for Sensing Manhole Gases
Varun Kumar Ojha, Paramartha Dutta, Atal Chaudhuri +1
Human fatalities are reported due to the excessive proportional presence of hazardous gas components in the manhole, such as Hydrogen Sulfide, Ammonia, Methane, Carbon Dioxide, Nit…
ACO for Continuous Function Optimization: A Performance Analysis
Varun Kumar Ojha, Ajith Abraham, Vaclav Snasel
The performance of the meta-heuristic algorithms often depends on their parameter settings. Appropriate tuning of the underlying parameters can drastically improve the performance…
Simultaneous Optimization of Neural Network Weights and Active Nodes using Metaheuristics
