Neural network design using matlab

I want to get the weights between the last hidden layer and output layer from the deep neural network designed using matlab codes.

I have tried with net.LW but it is returning the weights between 2 hidden layers.

Solution

  • You can use net.LW to pass in two indices to get the weights between two layers.

    net.LW{i,j}

    Use numel(net.layers) to get the number of layers. This will be the index of the output layer. One less is the index of the last hidden layer.

    j = numel(net.layers)
i = numel(net.layers) - 1

net.LW{i,j}

    You can update with variables for your app.
