Let’s take a simple linear regression model with a handful of parameters. The weights could be an array of maybe 5 numbers. Should that be copyrightable? What if someone else uses the same data sources (e.g. OSS data sets) and architecture and arrives at the same weights? Is this a Copyright violation? Let’s talk about more complex models. What if my model shares 5% of the same weights with your model? What about 50%? What about 99%? How much do these have to change before you’re in the clear? What if I take your exact model and run it through some extra layers that don’t do anything, but dilute the significance of your weights? It’s a murky area, and I’m inclined to think copyright is not at all the right tool to handle the legality of these models (especially given the glaring irony they are almost all trained using copyrighted material). Patents, perhaps better suited, but I’m also not sold.
