How to train neural network in MATLAB in mutliple levels?

I am using Neural Network to classify the images.

I want to train the NN in 3 levels.

• Level 1. train using 3 categories of images
• Level 2. 3 categories
• Level 3. 2 categories

What is the approach I should follow?

Please suggest.

It will not work. Significant characteristics of all 8 categories should be continually present.

You haven't explained what the images contain, what the categories are and why you want to do this.
