2.算法涉及理论知识概要

       数据采集：获取肉类样品在不同新鲜度阶段的图像数据，通常使用高分辨率相机拍摄并标注对应的新鲜度等级。

 

      GoogleNet模型因其独特的“ inception ”模块而得名，这种模块设计旨在同时利用不同尺度的特征。传统的卷积层在同一层面上使用固定大小的滤波器，而Inception模块则在一个模块内部集成多种大小的卷积核以捕获多尺度信息。

 

Inception模块

       一个基本的Inception模块可以包括1x1、3x3和5x5卷积层，以及一个最大池化层，所有层的输出都会进行线性组合。例如，对于一个通道数为c 的输入特征图，其经过1x1卷积层（用于减少计算量和维度），3x3和5x5卷积层进行特征提取，以及最大池化层后，各层输出分别记作 a,b,c,d，尺寸分别为′a′,b′,c′,d′，则总输出O 可以表示为：

GoogLeNet模型结构

       整个GoogLeNet模型由一系列堆叠的Inception模块构成，还包括了辅助分类器以增强梯度传播和模型训练。每一层都有批量归一化（Batch Normalization）和ReLU激活函数进行非线性变换。

 

肉类新鲜度检测应用

       在应用于肉类新鲜度检测时，首先将肉类图像输入到GoogLeNet模型中，通过多个层级的特征提取，模型最终会在顶层生成一个表示新鲜度等级的概率分布。假设我们有 K 类新鲜度级别，则输出层通过softmax函数给出各个级别的概率：

训练过程

模型的训练目标是最小化交叉熵损失函数：

3.MATLAB核心程序 `% 设置训练选项

maxEpochs = NEpochs;

Minibatch_Size = NMB;

Validation_Frequency = floor(numel(Resized_Training_Dataset.Files)/Minibatch_Size);

Training_Options = trainingOptions('sgdm', ...

    'MiniBatchSize', Minibatch_Size, ...

    'MaxEpochs', maxEpochs, ...

    'InitialLearnRate', LR, ...

    'Shuffle', 'every-epoch', ...

    'ValidationData', Resized_Validation_Dataset, ...

    'ValidationFrequency', Validation_Frequency, ...

    'Verbose', false, ...

    'Plots', 'training-progress');

 

% 使用训练选项训练网络

net = trainNetwork(Resized_Training_Dataset, New_Network, Training_Options);

% 保存训练后的网络
