摘要: 提出一种一般二进制映射问题的前馈网络学习算法.给出一种求解超平面以几何分 割训练点的新方法,不仅相应地构造了隐层神经网络,而且使得只需再构造一个输出层网络 便可实现训练样本所描述的映射.该算法在学习收敛速度方面优于BP算法和SC算法,对样 本数据的分布和密集程度变化适应性强,具有较好的容错能力.Abstract: A learning algorithm is presented for the general binary mapping problem. The algorithm employs a new method to compute hyper-planes to divide the training points into distinct areas so that the hidden layer of neural networks is correspondingly constructed. This makes it possible that only one output layer needs construction to implement the mapping determined by the training points. The algorithm is better than BP and SC algorithms in respect of the convergence velocity, is more adaptive to the change of the distribution and density of the training points, and has a better error-tolerant ability.
