Let's say I have written a NetChain machine learning setup, trained the chain with NetTrain and obtained a model ready to predict:

model = NetChain[...];
trained = NetTrain[model,...];

The whole process took a long time to prepare, so I do not want to repeat the same preparation steps the next time I start Mathematica. Is there a way to save trained and load from memory instead of recreating it?

    $\begingroup$ Pretty sure you can just save it via the normal routes, e.g. .m, .mx, compressed string, byte array. $\endgroup$ – b3m2a1 Sep 4 '17 at 5:10

Export[NotebookDirectory[]<>"mynet.wlnet",trained]

Just use Import on the same file to reload into memory.
