The mean grey value of ice is 154 using simulation of gauss error function 采用高斯誤差函數(shù)擬合,計(jì)算得到冰的平均灰度值為154 。
The error functions will return null if called outside the scope of a catch block 如果在catch塊的作用域之外調(diào)用錯(cuò)誤函數(shù),錯(cuò)誤函數(shù)將返回null 。
In this way , the establishment of the error function and the select of the optimization are important 在此方法中,主要是誤差函數(shù)的建立和優(yōu)化方法的選擇。
And we put forward a new algorithm that can solve the drawback of back propagation that easily converge to a local minimum point of the error function 而后針對(duì)bp算法易陷入局部極小的缺陷,提出了一種新的算法ambp算法。
If the status is anything other than success , the application can call the error functions , methods , or objects to retrieve the error information 如果狀態(tài)不是成功,應(yīng)用程序可以調(diào)用錯(cuò)誤函數(shù)、方法或?qū)ο髞?lái)檢索錯(cuò)誤信息。
Since it adopt the steepest descent method in nonlinear programming , it has the drawback that easy converge to a local minimum point of the error function 由于它采用非線性規(guī)劃中的最速下降法,因而存在極易陷入局部極小的缺陷。
Error functions can be referenced inside a stored procedure and can be used to retrieve error information when the stored procedure is executed in the catch block 在catch塊內(nèi)執(zhí)行存儲(chǔ)過(guò)程時(shí),可以在存儲(chǔ)過(guò)程中引用錯(cuò)誤函數(shù)并將其用于檢索錯(cuò)誤信息。
Combining absolute error function with relative error function , and setting it as the objective function of bp networks application to the flood forecast 綜合絕對(duì)誤差函數(shù)和相對(duì)誤差函數(shù)于一體,提出一種適合于水文研究的bp神經(jīng)網(wǎng)絡(luò)綜合目標(biāo)函數(shù)。
