MATLAB - How to retain trained neural network with new dataset

Question

I have trained neural network and i want to improve performance of network by retain trained neural network with new dataset. can i do this with command line not GUI.

For example: I have 3 dataset for training, 1.) input1 and target1 2.) input2 and target2 3.) input3 and target3

net=patternnet(20);
net=train(net,input1,target1);

After trained neural net with first dataset its performance is under expect so i want to improve trained neural net with dataset 2 and 3 by not change network structure. how can i do this?

Answer 1

If you want to train the NN with 3 datasets, why not to make one bigger dataset?

input = [dataset1; dataset2; dataset3];
target = [target1;target2;target3];

If you don't like this option, you can retrain network with matlab dedicated Neural Network Fitting Tool.
