I have a simple question about Mathematica 11.3. Is is possible to train a model of neural network with NetTrain in several steps like with Keras?

Perhaps do I have to (1) create my model, (2) train it, (3) create a new model like in (1), copy the weights from (2) to (3), reuse NetTrain ?

It seems that once a first training is done, all the weights and bias are fixed with Mathematica.

Thanks for your help, N.

    $\begingroup$ I am 90% certain it is possible to copy the weights from one net to another. Look up the "Net Surgery" tutorials and documentation. $\endgroup$ – b3m2a1 Jun 29 at 21:14
