So some take away points from the great community call today (thanks @femtomc and @cscherrer for organizing this):
1. There are plans to separate Gen's GFI to its own package at some point. CC: @alex…

The broad goals: (1) : remove the DSSM dependency from the tests after proving there is no weird interaction in the zygote gradients; (2) ensure simple unit tests exist so that if people tweak perform…

The chainrules crew tell me that it is now reasonable to pass in named tuples into AD, which might let us make a major syntax improvement in the DSL/perturbation solver proof of concept. Better to do…

There're two reasons for this:
* `ImageFiltering` is heavy; currently the only place it's used is `imfilter` in `SSIM`.
* To make `SSIM` compatible to `Zygote`, we might need to use a simplified …

Hello,
My first issue here . yay!!. I was thinking about ideas to inform the codebase about the availability of Jacobians from the forward solver. Some kind of flag? Also the size of Jacobians is dir…

I have encountered this issue several times. This is the smallest example I was able to find to reproduce it.
