总体而言,CNN用作特征(融合)提取,然后将输出的feature映射为序列向量输入到GRU当中。
%% 训练混合网络
% rng(0);
% 训练
CNNGRUnet = trainNetwork(XrTrain,YrTrain,layers,options);
%-------------------------------------------------------------------------------------
%% CNN-GRU数据输出
%% 训练误差集评价
ACCtrain = sum(YPred_Train == YrTrain)./numel(YrTrain);
disp('CNN-GRU训练ACC');
disp(ACCtrain)
%-------------------------------------------------------------------------------------
%% 测试集误差评价
ACCtest = sum(YPred_Test == YrTest)./numel(YrTest);
disp('CNN-GRU测试ACC');
disp(ACCtest)
结合CNN与GRU提出卷积门阀循环神经网络的本分类方法。通过引入卷积结构提取多尺度组合特征,辅助高层特征学习,从而丰富了GRU的特征输入。同时,引入Softmax分类器,使学习到的特征在类内紧凑。在后续研究中,还会继续优化和改进所提出模型的算法、结构与参数设置,以进一步提高模型分类识别能力。
