摘要：

This work describes what are the effects on the behavior of backpropagation rule of the constraints due to silicon implementations of Artificial Neural Systems. The effects on learning performance of limited weight resolution, range limitations, and the steepness of the activation function are considered. A minimum resolution of about 20 divided-by 22 bits is generally required but this figure can be reduced to about 14 divided-by 15 bits by properly choosing the learning parameter-eta. An algorithm is described which finds a near-optimum value for eta which attains good performance in presence of limited resolution; these performances can be further improved using a modified batch backpropagation rule. Theoretical analysis has been compared with ad-hoc simulations and results are discussed in detail.
