正反馈与负反馈

但在语言模型框架下的正反馈与负反馈相结合的模型的研究在SIGIR中还不曾见到。

However under the framework of the language model , so far , it has not been seen in SIGIR to study on the mixture model of negative feedback and positive feedback .

文中论述了话语信息的控效和类型，根据信息反馈的顺序与功能区分出前反馈与后反馈、正反馈与负反馈，指出话语控制的机制实质在于负反馈。

We first discuss the controlling effect of utterance and the classification of utterance . Front feedback and back feedback , positive feedback and negative feedback are differentiated based on the order and function of feedback . We find that the mechanism of utterance control lies in negative feedback .

加速度正反馈与近似积分负反馈相结合的综合加速度反馈在机械手位置控制中的应用有明显的增阻尼效果，而在力控制中的应用却受到了很多条件的限制。

The application of integration acceleration feedback which combines acceleration positive feedback and integral negative feedback has obvious effect on enhancing damp in manipulators position control , but the effect is limited by some factors in force control .
