摘要： The learning algorithm called Expand-and-Truncate Learning (ETL) is invented to synthesize a three-layer threshold network (TLTN) with guaranteed convergence for an arbitrary switching function. There has not yet been found an algorithm to synthesize a threshold network for an arbitrary switching function. The most significant contribution of this invention is the development of a learning algorithm for a three-layer TLTN which guarantees convergence for any switching function, automatically determining a required number of threshold elements in the hidden layer. For example, it turns out that the required number of threshold elements in the hidden layer of a TLTN for an n-bit parity function is equal to n. The threshold element in the proposed TLTN employs only integer weights and integer thresholds. Therefore, this will greatly facilitate actual hardware implementation of the proposed TLTN using currently available digital VLSI technology.
摘要翻译：发明了一种称为扩展和截断学习（ETL）的学习算法，以合成具有任意切换功能的保证收敛的三层阈值网络（TLTN）。还没有发现用于合成用于任意切换功能的阈值网络的算法。本发明最重要的贡献在于开发三层TLTN的学习算法，保证任何切换功能的收敛，自动确定隐层中所需数量的阈值元素。例如，结果表明，对于n位奇偶校验函数，TLTN的隐藏层中所需的阈值数目等于n。所提出的TLTN中的阈值元素仅使用整数权重和整数阈值。因此，这将极大地促进使用当前可用的数字VLSI技术的所提出的TLTN的实际硬件实现。
