However, the conventional CMAC has an enormous memory requirement so that it cannot be applied to solve higher dimensional problems.

因此，本研究提出一个具有自组织能力之阶层式小脑模型类神经网路，它可以依据分析学习样本的分布，自动建立网路的记忆体配置，并藉由阶层式的学习架构，来有效降低记忆体的需求，使其具有解决高维度问题的能力，而此类神经网路架构亦具有可扩充性，可以在不影响其他网路的学习架构下，任意的增减输出节点的个数，此外，我们也提出了一个渐进式学习的演算法来训练此一类神经网路。
