A bit off topic maybe, but I think it is interesting to wonder what Free&OpenSource terminology means when it is applied in the context of ML : If you use a pre-trained model but you don’t have the original data, can
you call it FOSS ?
You have the source and can see every line of code, you know perfectly what are the inputs/ouputs, you can study the architecture, but at the same time you’ll never be able to change/improve the program (the ML part of it) if you cannot re-train.
