So, product rule is OK for taking the derivative of a dot product.

那么乘积法则对点乘求导没问题。

Well, then, dA, so we had to use the product rule carefully, or we use the partials.

那么对于dA，我们必须谨慎地使用乘法法则，或用偏微分。

The product rule is very simple and easy to implement, and it doesn't increase additional delay.

该“产生式规则”简单而易以实现，而且不增加浮点加法器的延迟。

The weight-based rule, the product rule and the model-based rule is established to present the knowledge.

系统采用了基于权重规则、基于产生式规则和基于模型的知识表示方法；

Leading zeros anticipatory logic is implemented based on a set of unified product rule, which can diminish the potential one bit error of original ones.

本文中的前导零预测逻辑是基于一套统一的“产生式规则”，可以消除原有前导零预测逻辑潜在的一位预测错误。
