How to design LSTM-CNN on deep network designer?

22 次查看(过去 30 天)
Hello,
My project is on classification of ECG/EEG signals using deep learning. I have design based on sequence on LSTM layer. Now i want to design hybrid LSTM-CNN on deep network designer which i have problem with connection between LSTM and Convolutional layer. I used Sequencefolding layer (suggested by deep network designer) after LSTM and connect to Convolutionallayer2d. The problem is Sequencefolding layer have two output (1. output, 2. minibatchsize) , which i don't now where to connect this minibatchsize connection. Can somebody expert give me advice on this? Really appreciate on any advice.
Thanks in advance sir.

You have to use a sequenceUnfoldingLayer that takes two inputs, feature map and the miniBatchSize from the corresponding sequenceLayer. You can refer to this example for more information.

Thank you very much for this sir. From the example given, it is for hybrid CNN-LSTM, what i'm try to design is LSTM-CNN....

Yeah i have try CNN-LSTM, but the input length must be not too long, otherwise will get out of memory even 32GB ram.

Hello Ali,
Evn I would like to apply CNN-LSTM network for the image data set classification problem. But unfortunately i am struggling to apply, can you please give me some insight, how can it be done?

% Load data
[XTrain,YTrain] = japaneseVowelsTrainData;
% Define layers
layers = [ sequenceInputLayer(12,'Normalization','none', 'MinLength', 9);
convolution1dLayer(3, 16)
batchNormalizationLayer()
reluLayer()
maxPooling1dLayer(2)
convolution1dLayer(5, 32)
batchNormalizationLayer()
reluLayer()
averagePooling1dLayer(2)
lstmLayer(100, 'OutputMode', 'last')
fullyConnectedLayer(9)
softmaxLayer()
classificationLayer()];
options = trainingOptions('adam', ...
'MaxEpochs',10, ...
'MiniBatchSize',27, ...
'SequenceLength','longest');
% Train network
net = trainNetwork(XTrain,YTrain,layers,options);
