Thirdly and ﬁnally: Since the layers are not in general fully connected, the nodes from layer k which innervate the jth node of layer j will in general be only a subset of the K nodes. And even thou you can build an artificial neural network with one of the powerful libraries on the market, without getting into the math behind this algorithm, understanding the math behind this algorithm is invaluable 誤差逆伝播法のアルゴリズム 1. ニューラルネットワークに学習のためのサンプルを与える。 2. ネットワークの出力とそのサンプルの最適解を比較する。各出力ニューロンについて誤差を計算する。 3. 個々のニューロンの期待される出力値と倍率(scalin Back Propagation Neural Network (BPNN) is a type of algorithm in Neural Network that can be use for Javanese alphabets character recognition.
