Ask HN: How do you license a neural network as free software?

I'm looking for how to use deep learning inside some open source software.

Has anyone done any work on the licensing of a trained network?

A network is effectively a piece of software, however it is based on both data and the training software. Of course, the training software can use any open source license.

Does the data it is based on need to have any particular kind of license or permission given?

And what license does the combined "binary" (it's effectively generated code) of the neural network itself have?

Are there any projects already doing this kind of licensing that do it well?
