    Can anyone tell me the advantages of neural network classifiers?

    Neural network with Softmax transformation, or probabilistic neural
    network, is used in many classification system.

    The basic idea is to train the network to approximate underlying
    conditional probability. Many training algorithms use KL difference
    between the true probability and the probability represented by the
    network. However, the true probability is unknown, so the frequency is
    used in KL difference. So, when network training finished, the
    probability represented by the network would be close to the
    frequency.

    Why not use frequency directly? What is the advantage of Neural network classifier?
