Loading and using pretrained networks

8 views (last 30 days)
I'm working with sets of 8 neural networks and when I load them all and try to use them Matlab doesn't recognise them.

Hi,
Can you provide the specific code you are using and the error message displayed in the Command Window. This will help in understanding the issue.

Hi,
From the example mentioned in the follow up, I think the trained network are not saved properly. Let say you have four trained networks in the workspace naming net1, net2, net3, net4. Then to save them in a single matrix you can use
save('networks.mat','net1','net2','net3','net4');
Afterwards if you want to load the networks into the workspace following command can be useful
load networks.mat
This will load all networks separately into the workspace.

There's no specific code Raunak. I trained a set of ANNs using the Deep Learning Toolbox and, one each was trained, I saved it using the 'save' command. Later, when I went on to use the trained networks I used the 'load' command at the Matlab prompt. When I tried to use the 'loaded' network I got 'Unrecognised variable or function'. Is it because I am trying to load several networks at once (8 in all)? I've managed to get round it by re-training the networks after issuing 'cleavars' and then applying them whilst they are still in memory (i.e. not specifically saving them). This works OK but this takes a long time!

Ah right. I hadn't realised that they needed to be saved as a linked set like that. I'll try that. Many thanks for your help Raunak.
