MATLAB: Classify requires at least 3 arguments

Question

Hi,

I am having trouble when trying to use the "classify" function to evaluate the performance of my neural network.

I am using the following code:

net = load('mynet.mat'); %this returns my previsouly trained SeriesNetwork object
test_folder = './test_data';
test_images = imageDatastore(test_folder,'FileExtensions','.jpg');
[Y,scores] = classify(net,test_images);

But the classify function throws me an error that it requires at least 3 arguments, which means it is trying to use the classify function from the statistics package.

What can I make do force the use of the classify from the deep learning package?

Thanks,

Raphael

Answer 1

net = load('mynet.mat'); %this returns my previsouly trained SeriesNetwork object

Not exactly. The output of load applied to a mat file, is a struct that has one field for each variable loaded. So you would need net.net where the first net is the struct returned from load and the second is the variable loaded.
