Abstract
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.
