在MATLAB中,dlarray(deep learning array)是一种特殊的数据结构,用于支持深度学习的操作。dlarray对象包含数据以及与之关联的尺寸和通道维度信息,这些信息对于深度学习中的操作(如卷积、池化等)非常重要。 要将dlarray对象转换为double类型,你可以使用gather函数,该函数可以将dlarray中的数据提取出来并转换为普通的数值数组...

A deep learning array stores data with optional data format labels for custom training loops, and enables functions to compute and use derivatives through automatic differentiation. 简言之,你可以用dlX = dlarray(X, fmt);将一个类型为single或double或logical的普通array(可以是gpuArray,支持复数),转换为...

x = dlarray(x,newdims); end As a final note - I notice you're concatenating the feature input layer to itself, alongside the outputs of layer 'fc2'. Maybe that's intentional, it seemed slightly curious to me. More Answers (0)
