Hi, I train an autoencoder in matlab R2016a and I want to change some weights of encoder or decoder and flip them to zero or one, but by doing it, I saw this error"You cannot set the read-only property 'EncoderWeights' of Autoencoder.". I need to change the weights and consider the changes. how can I do it? is there any way to solve this problem? thanks.

Hi Nadia

Unfortunately, you cannot directly modify the weights of an autoencoder in MATLAB. The 'EncoderWeights' property is read-only, which means you cannot change its values. However, you can train a new autoencoder with the desired weights by specifying the 'EncoderWeights' option during training.

Here's an example:

% Create and train an autoencoder
autoenc = trainAutoencoder(X, hiddenSize);
% Modify the weights
newWeights = ones(size(autoenc.EncoderWeights)); % Set all weights to 1
% Train a new autoencoder with the modified weights
newAutoenc = trainAutoencoder(X, hiddenSize, 'EncoderWeights', newWeights);
