Would it be possible to get some code like below working? The first example with the function `f` is meant to show that this definition of `hessian_vector_product` can work. The second example shows t…

Can we compute the Hessian? Can we compute a Hessian Vector Product?
What's the interface to do this?
Request from @rgiordan.

@vchuravy found how to use Enzyme.jl for JVP and J'VP.
We just need an HVP (hessian-vector product) now to update both examples in the documentati…

May I ask how to calculate the hessian of each layer on the popular llm models, such as llama. Or do you have some suggestions on the popular hessian calculation repo.
Thank you very much for you…

In the original paper, the authors claimed that MAML needs second gradient and Hessian-vector products. Could you explain how do you implement this or Pytorch just do this automatically? Thanks!

I saw in the [docs](https://linearsolve.sciml.ai/stable/) that "the current algorithms should support automatic differentiation," and played around with it a bit. My ultimate goal is to get a Hessian-…

I'm attempting to compute Hessian vector products for use with RL algorithms like Natural Policy Gradient or TRPO, but have been entirely unsuccessful.
Following https://github.com/FluxML/Zygote.jl…

Thanks, again, for this great tool.
I'm interested in computing purely mixed second derivatives. For example, if I have a function:
f(x₁,x₂,y₁,y₂,y₃)
then I'm interested in the rectangular ma…

#### Summary:
Once the ```stan::model``` class has implemented Hessians and Hessian-vector products, expose them in the ```rstan``` ```modelfit``` class. See https://github.com/stan-dev/stan/issues…
