Two cases are commonly distinguished, depending on whether the equation is linear or not.

回归也是类似的，但考虑到该数据是不精确的。鉴于一些要点，并测量值的一些功能在这些点，我们要确定未知函数。

The so-called linear, is an unknown function appears in equation and its derivative all once.

所谓线性，是指方程中出现的未知函数及其导数都是一次的。

The design of linear functional observer for time-delay systems with unknown inputs is concerned.

考虑了含未知输入的时滞系统的线性函数观测器设计。

Another reason is that the degree of linear independence of the variable basis functions composed by sigmoid functions decreases as the hidden nodes increasing, and this lead up to the inferior matrix condition number during learning, which forces the learning step length to decrease and the convergence speed to slow down.

一是因为未知系统复杂时需要较多的隐节点，从而学习的参数过多减慢了学习速度；另一个原因是随着隐节点数增加，由Sigmoid函数构造的可变基函数线性无关程度减弱，从而导致学习过程中矩阵条件数变差，迫使学习步长减小，收敛速度不得不减慢。
