They’re not data though, they’re coefficients. They are the only thing that significantly differentiates one model from another. If I told you the economy can be accurately modelled by GDP(x) = Ax + B But I don’t define A And B for you because it’s proprietary, you haven’t learned anything other than what you can glean from the structure of the model itself (it’s linear, there’s only a single input etc) If most of these models are similarly structured, I’d say the weights are the program.
