hai i have a doubt in neural network. i have 3 columns of input vector for which the target value is from 1 to 3 for each row. As shown below if the row vector is 2 4 and 7 the output should be 1. if it is 4 7 8 the output should be 2. neural network worked fine with this type of data.
2 4 7 1
4 7 8 2
2 5 9 3
now i have another set of data for which i have two row vectors with the same target value.
2 4 7 1
and also
6 7 2 1
with the same target 1. the same will continue for the whole row vectors sometimes there is same 3 target values for different row vectors. should i make some modification in the input data? will the neural network work for this type of data. i tried but i dont get near exact values. please help in this regard

All that can be guaranteed (if you design enough nets with different random initial weights and numbers of hidden nodes) is that the mse will be minimized to a reasonable degree of accuracy.
Hope this helps,
