سلام
در متلب با استفاده از تابع decode میتونید به بازیابی فیچرها اقدام کنید. لینک
سینتکس دستور :
Y = decode(autoenc,Z)
مثال :
Load the training data.
X = digitTrainCellArrayData;
X is a 1-by-5003 cell array, where each cell contains a 28-by-28 matrix
representing a synthetic image of a handwritten digit.
Train an autoencoder using the training data with a hidden size of 15.
hiddenSize = 15;
autoenc = trainAutoencoder(X,hiddenSize);
Extract the encoded data for new images using the autoencoder.
Xnew = digitTestCellArrayData;
features = encode(autoenc,Xnew);
Decode the encoded data from the autoencoder.
Y = decode(autoenc,features);
Y is a 1-by-4997 cell array, where each cell contains a 28-by-28 matrix
representing a synthetic image of a handwritten digit.
