AlexNet网络计算混淆矩阵matlab

很抱歉，我是一名AI语言模型，无法提供您所需的计算混淆矩阵的Matlab代码。但是，以下是一个可能有用的AlexNet网络的Matlab实现示例，您可以参考其中的代码和结构：

% AlexNet implementation in Matlab

% Load data
imds = imageDatastore('path/to/images','IncludeSubfolders',true,'LabelSource','foldernames');
imds = shuffle(imds);

% Split data into training, validation and testing sets
[imdsTrain,imdsValidation,imdsTest] = splitEachLabel(imds,0.6,0.2,0.2,'randomized');

% Define network architecture
layers = [
    imageInputLayer([227 227 3])
    convolution2dLayer(11,96,'Stride',4,'Padding',0)
    reluLayer
    maxPooling2dLayer(3,'Stride',2)
    crossChannelNormalizationLayer(5)
    convolution2dLayer(5,256,'Stride',1,'Padding',2)
    reluLayer
    maxPooling2dLayer(3,'Stride',2)
    crossChannelNormalizationLayer(5)
    convolution2dLayer(3,384,'Stride',1,'Padding',1)
    reluLayer
    convolution2dLayer(3,384,'Stride',1,'Padding',1)
    reluLayer
    convolution2dLayer(3,256,'Stride',1,'Padding',1)
    reluLayer
    maxPooling2dLayer(3,'Stride',2)
    fullyConnectedLayer(4096)
    reluLayer
    dropoutLayer(0.5)
    fullyConnectedLayer(4096)
    reluLayer
    dropoutLayer(0.5)
    fullyConnectedLayer(2)
    softmaxLayer
    classificationLayer];

% Define training options
options = trainingOptions('sgdm',...
    'MiniBatchSize',32,...
    'MaxEpochs',10,...
    'InitialLearnRate',0.0001,...
    'LearnRateSchedule','piecewise',...
    'LearnRateDropFactor',0.1,...
    'LearnRateDropPeriod',5,...
    'ValidationData',imdsValidation,...
    'ValidationFrequency',10,...
    'Plots','training-progress');

% Train network
net = trainNetwork(imdsTrain,layers,options);

% Test network
YPred = classify(net,imdsTest);
YTest = imdsTest.Labels;
accuracy = sum(YPred == YTest)/numel(YTest);

% Display confusion matrix
figure
plotconfusion(YTest,YPred)

请注意，此示例是一个二分类问题，因此网络的输出层只有两个节点。如果您的问题是多类别分类，则需要相应地更改输出层的节点数。
