APPENDIX A - RAW DATA.xlsx

I want to use three datasets in the model development; the worked hours, the loads and the fuel consumed by the truck.I want to use the worked hours and loads as the inputs(Two Inputs) and the fuel consumed as the target(output data). my dataset is consist of 80 records and i want to divide it into two sub datasets:training and testing. 65% of the total data for training and the remaining 35% for testing so as to validate accuracy of the model.The number of neuron in the hidden layer should be set to 1 initially and the hyperbolic tangent sigmiod function should be used as the transfer function.The data should be run to be run to give an output with the calculated error between the target and the output(predicted). The error should then be back propagated through the network for adjustments.The process should be repeated by varing the neuron number till the error is minimal. The model should then be simulated to ascertain the validity by using the testing data.The optimim number of neuron that gives the best results should be selected based on the correlation coefficient and the mean absolute percentage error for the testing data.The architecture of the BPNN should be developed.Find the data to be used in is below
