神经网络在训练中使用计算图，其中运算在正向传播中链接。反向传播然后通过在每个节点应用链式法则、乘以局部梯度来计算导数。此方法应用于更新用于医学图像分析的卷积网络中的参数，特别是用于检测早期肿瘤。 AI

影响这解释了神经网络的核心训练机制，对于理解人工智能模型开发和应用至关重要。

排序理由该条目描述了神经网络训练的基本机制及其在特定领域的应用，属于研究范畴。[lever_c_demoted from research: ic=1 ai=1.0]

Neural networks train by constructing a computational graph in the forward pass, chaining basic operations such as x × y × z into composite functions of the inp

Neural networks train by constructing a computational graph in the forward pass, chaining basic operations such as x × y × z into composite functions of the inputs. Derivatives of the output with respect to every input are then obtained in the backward pass by applying the chain …
