I use Matlab Classification Learner to train various different models on an experimental dataset. The models are successfully exported from the app to the workspace and I am able to use them to make predictions for new datasets. The problem arises when I try to save the models. Some of them need around 2 minutes to get saved while others cannot be saved at all. I do not receive any error, the computer appears to be busy, the new file is created but is only 1KB in size. When I check the 'saved' model it appears that the model was not saved properly and cannot be used.
Did anyone have a similar experience to mine.
PS1: The models I managed to save are large, ranging from 672MB to 1.7GB. The ones I cannot are probably bigger.
PS2: Thank you in advance for any answers.

Hi,
you could consider to export a compact model without the training data - this will also work for making predictions on new data:

This should help to decrease the file size.
Best regards
