TVB doesn't provide estimation for the moment. You can use TVB with gradient free and likelihood free techniques like SBI (https://www.mackelab.org/sbi/) or write the model equations as components
in a framework like Pyro. You can find examples in the BVEP repo,
I'd suggest searching for "feature engineering" for the general principles. After that you'd want to choose features relevant to this domain such as FC and PSD, etc. Multiple can be used with SBI, but I don't expect it to generalize (reproduce features
not provided as input).
