Tensorflow tf.nn.atrous_conv2d如何实现空洞卷积的
在训练UNET网络时,可以通过定义一个cell数组来包含训练数据和验证数据。在这个cell数组中,第一个元素是训练数据,第二个元素是验证数据。因此,在这里可以定义valvol,如下所示:
```
% 定义训练数据和验证数据
trainData = {data.trainvol, data.trainseg};
valData = {data.valvol, data.valseg};
% 定义训练选项
options = trainingOptions('adam', ...
'MaxEpochs', 50, ...
'MiniBatchSize', 16, ...
'InitialLearnRate', 1e-3, ...
'Shuffle', 'every-epoch', ...
'ValidationData', valData, ... % 将验证数据作为选项输入
'ValidationFrequency', 10, ...
'Verbose', true, ...
'Plots', 'training-progress');
% 训练UNET网络
unet = trainNetwork(trainData, layers, options);
```
在这里,我们将验证数据作为选项输入,并在训练过程中每10个epoch进行一次验证,以便监控模型的性能。
