Hello guys,
i want to train my LSTM using double precision but the deep learning toolbox only allows single precision. Can i change that to double precision or how do i train my neural network using double precision ?

This is possible with a dlnetwork but it is (currently) more of a workaround than anything else. Once your dlnetwork is ready to go, convert it to double precision:
net = dlupdate(@double, net);
net.State = dlupdate(@double, net.State);
Then make sure your input data to the network is always in double precision. Everything should then remain in double as you train and use the network.
Let me know if this doesn't work for you.
