To achieve this goal , this paper design a neural network with three layers in which the first layer play a classifier role and learn with the memory - based learning algorithm while the second and third layers learn with the error back - propagation algorithm 根據(jù)這一需要,本文建立了三層神經(jīng)網(wǎng)絡(luò),第一層起分類作用,采用基于記憶學(xué)習(xí)算法,第二、三層采用誤差反饋學(xué)習(xí)算法。
