how to reload saved ANN model in workspace properly

I am not able to load the saved ANN model on the workspace . The "net" file does not appear only input , output and results. (check the image)

Answer 1

It looks like your network was not saved in your mat file. What code did you use to create the mat file? Had your network variable been created at the time you create the mat file?

Here's an example from this answer.

load breakersize2.mat

out = net([1;1])

out = 1.0344

i didn't use code to generate the ANN. This is what I have done

(1) define variable "input" and "output"

(2) nftool

(3) import data in neural network window

(3) train

(4) export to workspace (the problem is only struct file is getting transfer to the workspace)

Answer 2

Suppose that you exported from nftool to the variable named results then

net = results.Network;

[Sunita]

this is what i did :

1) nftool

2) train model and export to workspace (name : results)

3) right click on results in workspace then save in folder

4) load results

5) net = results.Network (got the network file)

6) load net - nothing happens

[Walter Roberson]

You would not load net because net is already the saved network after the assignment statement.

Likewise you would not load results because results is already in your workspace from your export operation in nftool.

[Sunita]

got it , but the problem is still the same , I am not getting the complete variables files if it is exported from neural netwok window (nftool).

[Walter Roberson]

Fine. Then after you get results extract Network from it into net and save it to a mat file just so that you can still l file to load()

[Walter Roberson]

x = rand(4,241);
y = randi(3, 1, 241);
nftool
%Import -> Import Data, select x and y, Observations in Columns, OK
%Train
%Export Model -> Export to Workspace, variable named results
net = results.Network;

predicted_y = round(net(x));
accuracy = mean(y == predicted_y) * 100  %percent
