question about Hessian-vector products

[shawnkx]

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!

@shawnkx Does the official MAML git repo. implement hessian vector product ? I forgot already.

The results in the original paper claim K-shot, which comes to a doubt that the K means the number on the stage of meta-training or meta-testing (fine-tuning) with regard to the different shot number in the code.

In the official MAML you can choose whether to use second order deriative as follows
