Here's how the gradient flow for minimizing KL(pi, target) looks under the Fisher-Rao metric. I thought some probability mass would be disappearing on the left and appearing on the right (i.e. teleportation), like a geodesic under the same metric, but I was very wrong... What's the right intuition?

This afternoon I was privileged to examine Alex Glyn-Davies, who produced a great thesis on aspects of physics-informed inference for DE models (arxiv.org/abs/2209.15609, arxiv.org/abs/2409.07101 and arxiv.org/abs/2409.06560) and some anomaly detection for good measure doi.org/10.1016/j.pa....

$Φ$-DVAE: Physics-Informed Dynamical Variational Autoencoders for Unstructured Data Assimilation

Incorporating unstructured data into physical models is a challenging problem that is emerging in data assimilation. Traditional approaches focus on well-defined observation operators whose functional...

If anyone is thinking of registering for this, I understand that there are still some spaces available, but the room this event is taking place in has a limited capacity which is likely to be reached... so to avoid disappointment it would be safer to register sooner rather than later ;-).
