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
创建一个(深度学习工具箱) minibatchqueue对象,用于管理自定义训练循环中的小批量样本。minibatchqueue对象还将数据转换为(深度学习工具箱)dlarray对象,该对象可在深度学习应用程序中实现自动区分。 将小批量数据提取格式指定为 ' SSCB'(空间、空间、通道、批处理)。将 'DispatchInBackground'名称-值参数设置为由canU...
看得多了我就发现,他们用来计算梯度的因变量和自变量是有显式关系的,这点我通过直接将loss设置成一个dlarray的值来确认,如loss=dlarray(2.45,'CB'),结果发现程序报错,所以我以矩阵运算的形式,求交叉熵loss=mean(sum(-labels.*log(out))),程序能够运行成功。但是你将变量带入netLoss_cal函数,计算loss,依旧会报...
