输出层偏导数：首先计算损失函数相对于输出层神经元输出的偏导数。这通常直接依赖于所选的损失函数。
算法从输出层开始，根据损失函数计算输出层的误差，然后将误差信息反向传播到隐藏层，逐层计算每个神经元的误差梯度。

参数偏导数：在计算了输出层和隐藏层的偏导数之后，我们需要进一步计算损失函数相对于网络参数的偏导数，即权重和偏置的偏导数。
Backporting can provide consumers a Phony perception of protection In the event the enumeration system just isn't thoroughly comprehended. By way of example, customers back pr may well read through media reviews about upgrading their program to handle security challenges. Having said that, what they actually do is install an current deal from the vendor and not the newest upstream Variation of the appliance.
