Hi!
I have seen that within the 1.5.0 release, the possibility to compute HVP of a function has been added.
As far as I understand from the documentation, the HVP (as well as the VHP, VJP and so on) can be computed w.r.t. the input only, and not w.r.t. some other variable (such as, for instance, the parameters of a model). Is my understanding correct? Is there any way to use the built-in HVP (or VHP) function differentiating w.r.t. the model parameters?
Thanks!
