Hello I am using Excel for this and a custom function, my problem is the functions between I8 and AV9 altought some of them appear to work, sometimes they are giving me the Value Error. I think this ... IsaacPiscopoI believe that formula was also incorrect. At the very least I notice...

一、Cost Function(代价函数) 1、首先介绍两个术语:L和 (1)L是神经网络的层数 (2)是指第L层的单元数目(不包括偏置神经元) 上图是二元分类和多元分类中K值和SL的比较 2、下图为神经网络代价函数和逻辑回归代价函数 神经网络代价函数和逻辑回归代价函数的区别是将假设函数h(x)输出的每一个元素都加起来。 注:...
3. 假设函数(hypothesis function):在监督学习中,为了拟合输入样本,而使用的假设函数,记为hθ(x)。比如对于样本(xi,yi)(i=1,2,...n),可以采用拟合函数如下: hθ(x) = θ0+θ1x。 4. 损失函数(loss function):为了评估模型拟合的好坏,通常用损失函数来度量拟合的程度。损失函数极小化,意味着拟合程度...
