Abstract: Artificial Neural Networks (ANN) are recognized extensively as a powerful tool for most of the research applications including classification of heterogeneous data using function approximators. Identifying better neural classifier architecturefor a given input data depends on many factors, including the complexity of theproblem, the training set, the number of weightsand biases in the network and the error goal. Feedforward networks frequently exercise classification techniques for complex non-linear data. This paper presents a comparative study of different type of Feedforward neural networks such as Simple Feedforward networks, Pattern recognition networks and Cascade forward networks in classifying the global carbon emissions data. In this study the percapita carbon emissions of several countries are classified into low, medium and high category. Levenberg-Marquardt learning algorithm is used to train these networks as it is the fastest and first choice supervised learning algorithm with less training errors. Hyperbolic tangent activation function is used in this study because of their massive interconnectivity and enhanced processing performance. Experimental results show that simple Feedforward network outperformed in less number of epochs with higher classification accuracy.
