## Information Geometry

The unholy offspring of Fisher information and differential geometry, about which I know little except that it sounds like it should be intuitive. See also information criteria. I also know that even though this sounds intuitive, it is not mainstream and it has also not been especially useful to me even in places where it seemed that it should, at least not beyond the basic delta method.

## Homogeneous probability

Albert Tarantola’s baby, from his maybe forthcoming manuscript. How does it relate to information geometry? I don’t know yet. Haven’t had time to read. Also not very common.

## Hamiltonian Monte Carlo

Are we talking about a similar thing with Hamiltonian Monte Carlo? That is very mainstream.
