The partial derivatives of z are very important because they are used to find the PNN weights during training. The figure below shows the output of a PNN when the m input case is applied. |

Problem 1 |

Proof the z_{mi} is equal to one when m is equal to i. |

Problem 2 |

Proof that the partial derivative of z_{mi} with respect to the weight w_{r} is given as follows. |
