The answer to your question is :
Yes it is possible to do.
HOWEVER, there is no MATLAB function available for doing so.
THEREFORE you would have to write your own code.
From ~1983 to ~2003 I wrote evolving versions of Gaussian hidden node classifiers for classifying radar targets. Most of the evolution involved updating the classifiers when new radar data on old target types became available. Less often new classifiers had to be designed when data on new target types became available.
The simplest versions were comparable to variations of MATLAB's NEWRB and NEWRBE.
If you are going to modify network geometry during training. I recommend using Gaussian hidden nodes and a combination of NEWRB and NEWRBE.
1. Classify inputs using Gaussian hidden nodes.
2. Misclassified inputs are used to add new Gaussian hidden nodes.
3. There are many ways to determine where and when a Gaussian hidden
node should be added or removed.
In summary, if you are going to remove and/or add network connections during training, I recommend using Gaussian hidden nodes in the fashion of NEWRB and NEWRBE.
Hope this helps.
Thank you for formally accepting my answer
