中文说明：有导师学习神经网络以其良好的学习能力广泛应用于各个领域中，其不仅可以解决拟合回归问题，亦可以用于模式识别、分类识别。本章将继续介绍两种典型的有导师学习神经网络（GRNN和PNN），并以实例说明其在分类识别中的应用。
English Description：
Supervised learning neural network with good learning abilities are widely used in various fields, which can not only solve regression problems, and can also be used for pattern recognition, classification and identification. This chapter continues with two supervised learning neural network (GRNN and PNN) and to illustrate its application in the classification.
