Hello,
I need to model a hysteresis curve by LSTM neural network can anyone help me with that?
I've read matlab documentations but unf I could'nt find my case. In face I don't know how to define properly network architucture (layer's).
Thanks for your help

Hi behrad,
It is my understanding that you want to build a Long Short-Term Memory (LSTM) Network to model a hysteresis curve using your data.
Below are high level steps to build an LSTM Model to model the hysteresis curve:
- Preprocess Data: Normalize the data if necessary and structure it into sequences that the LSTM can process.
- Create a sequence-to-sequence LSTM network architecture using Deep Learning Toolbox. The design includes choosing the number of LSTM layers, the number of hidden units in each layer, and other hyperparameters.
- Train the LSTM network using the training data.
Please refer to the pseudo code in the code snippet below: -
% Normalize data (if necessary)
inputDataNorm = normalize(inputData);
outputDataNorm = normalize(outputData);
% Prepare sequences - t
XTrain = ... % Your input sequences
YTrain = ... % Your output sequences
% Define LSTM network architecture
layers = [
sequenceInputLayer(size(XTrain,1))
lstmLayer(50,'OutputMode','sequence')
fullyConnectedLayer(1)
regressionLayer
];
% Specify training options
options = trainingOptions('adam', ...
'MaxEpochs',100, ...
'GradientThreshold',1, ...
'InitialLearnRate',0.005, ...
'LearnRateDropPeriod',125, ...
);
% Train LSTM network
net = trainNetwork(XTrain, YTrain, layers, options);
Please refer to the documentation below to learn more about LSTM Network.
Please refer to the documentation below to learn more about "lstmLayer".
Hope it helps!
